I need that array interpolated to say 20 data points but the first and 20th data point must be the actual first and last data point of the array (1 & 9 in the example). I have downloaded the xlfun software but the interpolat function only does 1 point at a time...than as you drag the function down it changes the initial array. Of course I realy have anywhere from 40-60 data points to be interpolated to 100.
With a known X and Y, trying to solve for Z from a table. ie: IF a variable X is defined across a row, another variable Y defined down a column, the data field Z fills in-between. What do I need to use to interpolate for both X and Y to solve for Z?
I need to know if there’s a function (or method) in excel that’ll allow me to select an array of numbers and once those numbers are selected, to use only the numbers (for an averaging function) that yield the best sigma?
I just have a quick question with regards to two-way interpolation of data.
I have a data table which has x-values, y-values and z-values.
I need to obtain an interpolate value for z, given a value for x and a value for y.
The x value specified is 1.569 and the y value specified is 1.66.
I know how to use the FORECAST formula for a simple x, y table, but I have no idea what to do here when I need to find a z value, given the x and y values.
I have data essentially comprising a set of points with x and y coordinates. Is there a way to index and interpolate between points?
I can use INDEX or LOOKUP to look up a y value fo a valid x value but don't know a way to interpolate if the value is between x values. Is this possible?
I got a table of two columns (A1:B6). One column (A1:A6) got temperature values and the other column (B1:B6) got enthalpy values as a function of temperature values as shown in the attached file. All values in the table are empirical values and I am trying to use them to obtain the enthaly (B11:B21) for my own temperatures (A11:A21).
I can use VLookup formula to do so but it won't be accurate because the enthalpy values are very sensitive to temperature changes. I need to use table A1:B6 and interpolate for temperature values that are located in between the integer temperature valuse. e.g. if the temperature=1.5 (between 1 and 2 in the table), how can I obtain the enthalpy value=15 (between 10 and 20) using the table.
i have a spreadsheet with a column of numbers in increments of 5 ie 25, 30, 35, 40, 45, 50, etc. and an adjacent column of decending numbers ie 275,273,262,250,238 where the numbers in column b decrease by varying amounts each time. for a given value say 37 i want to interpolate between the corisponding values of 35 and 40 to give an answer.
i'm trying to write a sheet that records weight from a date and user input trouble is people are likely to miss days out and i want to fill in the missing dates weight based on actual inputs from other days. if i make it easier and say it like this column A is the weight, column b is the number of days gone as an example i've made it straight forward but left 4 values out
I am looking to write excel function that would be able to interpolate between two list of values. One list containing xValues and another yValues and a x value the specified for which the appropriate y value is to be returned. For the moment I have written a short function interPLinear into which I wish to feed an array and then simply add those together. This is so that I can make sure that my syntax is correct. Unfortunately I am struggling with that at the moment. My function looks like this.
Function InterPLinear(xValues() As Double) Dim Sum As Double InterPLinear = 0 InterPLinear = InterPLinear + xValues(1) InterPLinear = InterPLinear + xValues(2) InterPLinear = InterPLinear + xValues(3) InterPLinear = InterPLinear + xValues(4) InterPLinear = InterPLinear + xValues(5) 'I know that there will be only 5 values, will make it generic at a later stage. End Function
In the spreadsheet I have created a short table with 5 rows and 1 column with values 1 to 5. In another cell I have entered the following =interplinear(A1:A5) and I have tried the following as well {=interplinear(A1:A5)} Could you perhaps tell me how I can correctly access this function so that it does not return #value
I have a question on data interpolation with Excel 2007. Normally, this wouldn't be too much of an issue for me, but for some reason I cannot figure it out.
I'm working on an Income Statement, which is designed for 5 years. I have values 1 and 5, which are given to me (B7: 3,500,000 and F7: 5,200,000). I'm trying to figure out the other 3 years of revenue assuming a growth trend. The values should fill the series B7:F7.
I have pasted 5 fields with some random values that are in A1 to E1. E is the column I am trying to populate to fill in the missing data for C.
I have written a function that will interpolate between 2 deltas using the dates. Assuming that June 09 will always have a corresponding delta (e.g. here 33) how can i populate the INTERP column using my YINT function. I can do this manually 1 at a time, but the already-filled cells in the Delta column will not always be the same and manually would take ages....
Actually, I've created the user defined function (UDF) to interpolate (both linear and bilinear). It's just, I keep getting this annoying error that says "A value used in the formula is of the wrong data type." But here's the kicker...I converted the UDF into a subroutine for trouble shooting, and I was able to step through the entire code and get the correct output.
Function itcinter(efpd As Single, pwr As Single) As Variant Dim rnge, mtrnge As Range Dim w, x, y, z, xx, yy, b As Single Dim scenario, a As Integer Dim J As Variant scenario = Worksheets("Input").Range("B1").Value pwr = pwr / 100# If (scenario = 1) Then Worksheets("ITC").Select 'Make table into a range for VLookUp Set rnge = Worksheets("ITC").Range("A3", [A3].End(xlDown).End(xlToRight)) Set mtrnge = Worksheets("ITC").Range("A3", [A3].End(xlDown)) 'If the given value does not match a table value exactly On Error Resume Next.......................
I have 5 worksheets each with tables that are formatted the same on each sheet. I have named each table as a named range (ex:filter5tsd15BSF). I have a userdefined function that interpolates values for a single table in a vba module. I can make this function work for a single table by calling the function as =Linterp(filter5tsd15BSF,C12) so I know the function is OK. However, I really rather program this some way that all the tables get passed to the function and then a select case for the conditions for which filter and which TSD (15 or 25) will then select the correct table.
I have 1-d array that gets populated from a number of sheets. This array may contain duplicate entries... for example, let's say this array contains animals.. cows, chickens, horses, pigs... etc. What I would like to do is take this info from this array and create another where it would contain all the different types of animals but without all the repeats.
I have account numbers in column A. I have 2 columns which contain account range.For example column/cell f1 contains 45555555 and column cell g1 contains 45666666. I have to check if the account in column A is in this range, and if yes ,I have to have "klo" in column B.
The problem is , that I have to check a lot of rows (and I do not mentioned but I have to check other attributes with the same structure as well) and the do- loop-if structure is rather slow. Could you tell me how can I solve this with say arrays-or with other method-which can boost my macro?
Lets say I need an array of 100 numbers from zero to 100. I want a mean of 75, and SD of 12. Or the same data based on a skewness and kurtosis value. Can I do that in Excel?
I'm just generating fake datasets for my stats class to analyze.
I have an array with an ubound of 10,000 because I will be loading a different amount of numbers each time I run the macro. Is there a way to tell the amount of digits filled inside the array if it is less than 10,000?
But when in column "A" is "Yes", I want to store in array each value within cell in B (in this example B2) to apply later a For/For Each over each number (in this example are 3 values only within cell B2), something like:
I'm using the vlookup function to pull numbers off an array. Is there a way that I can get the vlookup function to pick the smallest number greater than or equal to my Look_up value. If not is there a function that can do that?
I have a list of Items and the quantities of those items on one sheet. Each item has a section location number as well. (three Columns, Item, Quantity, and Section Location). the list can repeat the same item multiple times.
This is why I then have a summary sheet to uses a SUMIF formula to sum the quantities of a given item that are in a givin section. which my SUMIF Formula works great for. But my problem is some items have the word "LUMP" as its quantity and not a number. I want to add to my array formula so if the item does have a LUMP quantity and the lump quantity is in the section location to put LUMP on the summary sheet. here is my formula
projectInfo is the sheet where the list is. Column AE is the Item column on the projectinfo sheet column B on the summary sheet would be the item that i want to sum the quantities for Column AD is the section location column on the projectinfo sheet the AA$10 is the row and column of the section location i want to limit the sum of the quantities to the formula is in cell AA59 So it will sum all the quantities in the list on the projectinfo sheet if the item and section location match whats specified on the summary sheet.
getting LUMP to display if its a lump quantity. The Lump can only show up if the item on the projectinfo sheet has LUMP for that Item AND in that section location.
EDIT: Column AF on the ProjectInfo Sheet is the quantity column
Application.ScreenUpdating = False Dim c As String Dim d As String

this works perfectly but I have found one problem, I want excel to find on the existing arrays "0,00" and "0", only full match and not only partial like for example:
-154.09, which triggers "0" for the second array and 120,00, that triggers "0,00" how to I change to only find full match with the existing arrays?
in C a string is nothing more than an Array of characters ending with a null character.
in VBA this does not seem to be the case.I am trying to use the BlowFish code from David Midkiff for some encryption, however the code sometimes fails:
When encrypting a string a string of a specific length should be returned. however sometimes one of the characters of the encrypted string is a null character, and the returned encrypted string (with a embedded null character) is causing me problems. I want to check for the null character and if present redo the encryption. But how do I check for the presence of this null character in a unicode (double-byte) string?
Checking with Len(encrypted) gives the correct length (!) but trying to move each (unicode)character into an array fails when using the Mid() function past the null character in the string.
Now I can use
byteArray() = StrConv(unicodetext,vbFromUnicode)
to get the lower byte of each character into an array easily, but how do I do this for both bytes of the unicode characters?
Using an integer array does not work other than through
intArray(j) = CInt(AscW(Mid(Outp, j, 1)))
which fails on the nullstring in my encrypted text.
I have tried with variants but so far no luck. I thought if the string was entered into a variant then I could also address the variant as an array of bytes, but that does not seem to be accepted by VBA.
I am trying to populate many arrays with the same code using something like this. For this test, assume the following data in A1.
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
Code: Sub populate() Dim firstArr(5), secondArr(5), thirdArr(5), fourthArr(5), fifthArr(5) As Integer Dim r, c, num As Integer
[Code]....
The above code does not work of course and falls over. I am unsure whether I should try and concatenate with something like this eg "" & arrName(i) = Cells (r,c) or go down a different route.
I have a class module with several private variables, including one that is an array of a user-defined type. I am trying to set the values of a single element of this array with "Property Let ..." from a string array:
