## Finding two variables function  3-Visitor

## Finding two variables function

Hello

I would like to ask if is possible to find a function with two variables z(y,x) on Mathcad based on the data I have. It would be nice to find this function and with it to plot the surface.

Thank you and good weekend

Jonas

There is an infinite number of functions z(x,y) that pass exactly through the points you provide, two of them being:

z1(x,y)=1*y+0*x

z2(x,y)=0*x+1*y

Which one would you think Mathcad should find for you?

Success!

Hey Luc

Thanks for your answer, the numbers in that table are only representatives, in the data I have x,y and z have a different behavior.  23-Emerald II

I guess you are looking for an approximation.

Success!
