Hi,

Is it possible to fit 3D data(x,y,z) in Mathcad(v14)?

Under Insert > function I see only the 2D fitting functions.

You need a clearer definition of what it is you want to fit. You can fit just about anything using minerr.

As such, your demand is not interpretable. Better is a work sheet with an abstract description. What are x,y,z ?
