I need to take number in between cells. For example, I have numbers 1, 2, 3, 4, 5, 6, 7. When I type 5 in a column, I want to have 4 and 6, above and below 5. I am doing this to ease interpolation, so that whenever I want to do interpolation, I just need to type what number, I would like to have to be interpolated.
Attached file is the example : Matic Interpolation.xlsx
which function to use to find the row number of a value for interpolation.If I have a table of 5rows and 5 cols, how to find those rows of those 2 numbers between which my interpolation should be done.
X Y
2.2 3.45
2.9 4.56
3.3 6.2
3.7 7
4 8.1
Now I want to interpolate for 3.1. So how to find the row numbers of 2.9 and 3.3
what I have is a spread sheet of over 3000 numbers.
Now this is what the number looks like:
0000123456000
what I need is basically a formula or something to take out the zeros (They are not really zeros on the spreadsheet, its just an example to make it easier to display). And leave the six digits in the middle. Is this possible?
I have a dilemma. What I want to do is: If I input a date in a cell I want the adjacent cell to take the next highest number from a list on another worksheet. My example attached
View 3 Replies View RelatedI have created a simple spreadsheet to keep track of work hours. I simply enter in each days hours and then I get a total. I have each cell formatted for time (hh:mm). However it is annoying to have to type in the colon for each days time.
Is there a way I can just type in the three digits '9,3,0' into the cell and have it come out as '9:30'?
Formula that counts the number of people who are on my course and are taking their tests.
I have 5 classes, Class1, Class2, Class3, Class4 & Class5.
Column A details which class the pupil is in.
Column B details the pupils name.
Column C details the state of the course. This is either a DATE which they started, or "Paid" (they have paid for the course but not started), "Not Paid" (havent paid for course and havent started) or "In Progress" (Payment is in the process of being arranged).
Column D details the state of their final exam. This is either a DATE as to which they have finished and passed the exam, "Not Taken Yet" (Havent taken the exam yet) or "Fail" (They failed the exam).
This is where I am having problems, at the top of my sheet I want to summarise each classes statistics, but I am having problems with the COUNTIF. For example:
What formula can I use to add up the number of people in each class who have started the course?
E.g.
=countif(C10:C100," Is a Date ? ") AND is in Class1 ?
What forumla can I use to add up the number of people in each class who haven't passed the test ?
E.g.
=Countif(D10:D100,"Not Taken Yet" & "Failed") AND is in Class2 ?
I know I need an array to work this out.
And finally to really complicate things how about :
People in each CLASS who have STARTED the course (Date in C) AND haven't passed their test (Col D). I understand this is relying on a three part array whereas the others are 2 parts ?
I have data that consists of a set of coordinates that is indirectly related to an angular measurement. The data set that I have consists of four sets of coordinates and four coresponding angles. The data is below.
angle,43.09,34.83,26.8,18.08,
X,174.24,187.45,202.18,213.87,
Y,140.13,121.84,103.3,81.46,
How can I get excel to give me values for X and Y based on an angle that I input, such as 22.45. plotting a graph of the X and Y gives a curved output, so the methods that I know of do not seem to be working.
I have other more complex sets of data with complex curves that I would like to use a similar method to mine data.
I have a dataset of 360 columns and 180 rows in Excel 2007 and I want to increase the resolution of the dataset by 2 (i.e. I want to insert a value between each pair of cells, both vertically and horizontally). The calculation (interpolation) need not be complicated - I was thinking along the lines of a simple bilinear interpolation, where each new value is based on an average of the 4 cells surrounding it.
I'm fairly new to this type of operation in Excel, so I'd appreciate it if any responses I receive aren't too vague!
need an excel simple formula or function that returns values of y for given x in a two-dimensional array and works in the following way.actually a combination of linear interpolation and lookup/linear search. as in following example
x y
1 10
2 15
3 20
if x=1.5 then y=12.5 (answer available thru FORECAST but incomplete)
if x=2 then y=15 (answer available thru LOOKUP but incomplete)
so for whatever the x i need/get a valid y thru a single formula/method !
sorry m not good in math,
I have 3 equations and have created the relevant chart from them. What I would like to do is put in a value of x & y and get result z. Having done a search through previous threads I found some BiLinear Interpolation code that works using the table in a workbook, but what I'd really like is the Interpolation of the formulae rather than the resulting table and for it to be embedded in VBA.

View 5 Replies View Relatedinterpolating numbers in excel for an exponential function. I want to know how to be able to curve a curve in 4 different ways essentially the 2 that make up the two halves of a peak and the 2 that make up the two halves of a trough. I've tried using the LINEST function to create this interpolation and it's good to get 1 of the 4 curves I'm interested in. how to do the other 3? I'm also interested in knowing if these functions "whip the tail up" as in almost like how the tail end of a "sin" function flips back up. here it is.
[URL]
For this example of the exponential function, it creates the curve in one particular direction. I was wondering how I would do it to have it curve in another direction, for example I was testing the same function, but going downwards, and also having the tail curve back up (by hump I mean to simulate a gaussian distribution with the tails) how would I do that. seems like I now have part 1 of 4 aspects of the curve. here's the attached file to show what I mean. I want to get the hump going up and then sort of reflected along the y-axis and then similar features if I were to reflect the curves on the x axis. is it possible with the functions in excel?

View 6 Replies View RelatedI am looking for a VBA code which can be used to interpolate between values at a given interval and return these values to an excel sheet. I have a list with X and Y values and need to interpolate (linear) between two X points to return intermediate values for Y (interval between values is defined by the user in a userform). The code is to continue with interpolation between two consecutive X points until it has reached the end of the listing. In the example only several points are given, but the list can be longer or shorter than given in the example. The results need to be returned to a new sheet.

I am trying to develop a spreadsheet that will calculate a cost based on a matrix. I am attaching a sample of the calculation created so far. The end result is in cell M13 and is highlighted in yellow. I kind of layed the formula out in a few different cells, so hopefully it would be easy to follow.
simplify this process with maybe another formula that I might not be aware of, or maybe show me how to get this done in VB code. I think VB code would be the correct way to go just not sure.
However data now takes far too long to enter; for example if I type the number 9 into a cell it takes around 30 seconds to let me enter more data, it is as if it is working on some calculations. The VBA I'm using is as shown below.
View 3 Replies View RelatedI have a code below to only allow a number to be entered into one of 2 cells. I'm trying to do conditional formatting based on these to cells, and the evidence is showing that even when I type a value into either I21 or I22, they are taking on a value of zero.
I have conditional formatting stating that if I21>0, then do one thing. And in a separate cell, I have =I22>0, then do another thing. Neither works, and even using =I22<>0, then do formatting, and it doesn't work, telling me that the assumed value is always zero.
I need to calculate the average of 5 grades from A,B,C,D, and E. However I want it to the average even if any number of grades (i.e. up to 5) are entered.
e.g
grade1 grade 2 grade 3 grade 4 grade 5
A A C B E
I have assigned a vlookup table to convert to numerical values, and got it to calculate the average, but it falls apart when any grade is missing.
I have used the iferror command on the different calculations, but when i put them to gather into one large string, again it falls apart.
I've got a sheet which I need to analyse and split into several different sheets but the raw data format leaves a lot to be desired as there are blank rows inserted randomly between rows of data. I need the 'good' data to stay in the same order so I've written a macro to sort through the data and delete any blank rows leaving the good stuff behind.
The problem is this takes ages as there can be up to 30000 rows that need to be checked and I need to do this 5-6 times a day. I just wondered weather there was a quicker way to do this? The code I've got is detailed below:
Sub Prep2()
'Delete all blank data rows
Dim Rows As Double
Dim Rownum As Double
Application.ScreenUpdating = False
Rows = Selection.SpecialCells(xlLastCell).Row
For Rownum = 2 To Rows
If Cells(Rownum, 11) "" Then GoTo NxtRownum Else
Cells(Rownum, 11).EntireRow.Delete shift:=xlUp
Rows = Rows - 1
NxtRownum:
Next Rownum
Application.ScreenUpdating = True
End Sub
