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 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 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.

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

1
3
5
7
9
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?
View 9 Replies View RelatedI 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 attached the file if it is needed
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....

View 6 Replies View RelatedActually, 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.

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.

Assuming I have table with work weeks in the columns: WW01, WW02, etc.
And assuming I have few tools in a fabrique: A02, A08 etc.
Each tool have its own production value for each week: 12.15, 31.44, 17.98 etc.
I wish to built a function that will return me the best tool for a give WW with its value
To get the valus I used the functions:
=MAX(IF((F2:I2=D10),F3:I7))
=MIN(IF((F2:I2=D10),F3:I7))
And it worked okay (with ctrl-dhift-enter only)
To get the index I tried:
=INDEX(E3:E7,MATCH(MAX(IF((F2:I2=D10),F3:I7)),F3:I7,1))
=INDEX(E3:E7,MATCH(MIN(IF((F2:I2=D10),F3:I7)),F3:I7,1))
But the last argument must be an array. So I tried:
=INDEX(E3:E7,MATCH(MAX(IF((F2:I2=D10),F3:I7)),IF((F2:I2=D10),F3:I7),1))
=INDEX(E3:E7,MATCH(MIN(IF((F2:I2=D10),F3:I7)),IF((F2:I2=D10),F3:I7),1))
Still not working...
Not posted for a few weeks, its been crazy at work!
I have a problem!
What I want to do is use the MAX formula in C:C, but return the value to the left of =MAX(C:C)
I’m not brilliant with Index which is what I suspect I need to use
I am using sheet 1 to pull data from sheet 2 using this formula
=INDEX(Attendance!D:D,MATCH(C2,Attendance!A:A,0)).
This on its own works to pull the data. However the data is repeated for each 'set' of data ie each group of repeating names, as I drag down. I just want the data to appear once on the first lie of each group so I have added an if to the formula
=IF(C2=C1,"No Match",
My complete formula is now
=IF(C2=C1,"No Match",=INDEX(Attendance!D:D,MATCH(C2,Attendance!A:A,0))
I have the following data and i want to get the highest value over average using if, i wort this formula
=IF(INDEX(D3:D12,ROWS(D3:D3)>AVERAGE(D3:D12),"Greater","Lower"),
But it doesn't work.
The first sheet is called Sites and the second sheet is called Call Log-Jan-08
On the Call Log in cell A3 we put the division # and then we want the information to automatically fill out for the cells B3, C3 & D3. We want this information to come from the Sites list. In the sites list the information starts in A2 thru K2 (A1 thru K1 is the header info) and goes thru A645 thru K645.
I can't figure out how to get my Index formula to work.
On the attached workbook, on the "Progress Summary" page, cell C30 has a formula which should list the names of pupils who made 0 progress (as referenced by the Raw Data page, column R [progress] and column A [name].)

However, I need the following:
1. Only cells in the square range from B3 to G8 call the CalcValue when clicked.
2. Determine the index of each cell in the following way:
B3 is (1,1) and G8 is (6,6)

I have the following array formula that matches against a table with 3 criteria (one specfically is a time), it works ok until the time criteria is not of the value searched for, it may be +/- 30 minutes out, is it possible for the formula to index/match to the actual value or to find the nearest match possible, its in column B.
