Excellent examples

Worked for me but just because i have office 365 and I have search on Google "Microsoft AppSource store". Then there I look for ExceLab. Closed all the excel tabs before installing the add-in.

Hi though i have completed all steps, i am getting Value error, i am using excelab 365, with office 365

Search for "Calculus Functions Add-on" if you are using Google Sheets. "ExceLab" is nor found anymore.

Dear excel, first of all, thanks for teaching from you, how fix the value error for QUADF Function in excel, I have more complexity function and then can't detect error exactly is, while checked entire calculations from inputs to this error, please help me and of course I installed related add-in

By any chance, do you know how are this functions named in spanish Excel?. I've been seeking out this for a very long time. 😭 Or do you know if there is a function that does this on Python? thanks.

This function is amazing, saves me a lot of work... thanks..

hi

I can't get this to work. In the end I created a small test data set. If I use a formula like =INTERPXYZ(A2:B10,C2:C10,{0.2,0.5}) and press enter I get #VALUE! If I use a formula like =INTERPXYZ(A2:B10,C2:C10,D2:E4) and press Ctrl+Shift+Enter I get #NAME? I am using Office 365, downloaded the add-in from Microsoft app store, Acer laptop, Windows 10. I have been struggling with this for a couple of days now. Can anyone suggest what I might be doing wrong please?

I have been trying to get this to work for hours, I just get BUSY followed by #VALUE in the cell when I enter the formula. I am using Office 365 on an ACER laptop, I installed the add-in from the Microsoft app store. I have tried lots of different data sets. It's so frustrating. Any ideas what I might be doing wrong?

how you compute integral? mine showed busy

how can i insert IVsolve in the programm

I used this GRIDXYZ() as stated in this video to interpolate a f(x,y) function. I started from a (6 rows x 10 columns) table of x y with known z values in each cell and then built a 60x101 table of interpolated values to fill with GRIDXYZ. I chose an increment of 0.1, so I obtained a 60x101 table to fill, but when I use the GRIDXYZ function, I get "the allocated range is too small to interpolate grid z-values" Is it possible to contact you?

When we type X1 or Y1 as variables, doesn't Excel consider the CELL X1 and not the variable x?

I followed the exact instructions on this video, but I can't make the derivf function work for me. After a seemingly successful download, I do not see this Excel Lab program in my add-ins, nor can I find it manually by looking in C:\Program Files\ExcelWorks\ExceLab 7.0\bin or C:\Program Files (x86)\ExcelWorks\ExceLab 7.0\bin per the instructions. Any ideas on what I can try next?

Hi. i have (x,y,z) data from a survey (GPS) and in trying to use the given functions and it is not working. would you know why?

hi, i've tried using the IVSOLVE function with ExceLab 365 but it keeps returning a #VALUE! error. However, this function works fine when i have used it in google sheets. I have used the correct syntax for each too. Any help on solving the issue in ExceLab 365 would be appreciated.

First

I installed it, but, it said Error processing argument 3: Argument 3 reference must be a 2 column range of (x,y) interpolation data points. What should I do to fix this issue? ???

Are you in a hurry?

This is 2D interpolation, not 3D. Probably not buying anything from a math company that cannot tell the difference.

how to add thıs addition?

it shows the argument 3 should be a 2 column x,y value, why is that??
