Question: Curvefitting of 3D plot in Maple?

 

How to create a polynomial for the curve fitting of the 3D plot in Maple?

I have following data

a := [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

b := [ 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.001, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011, 0.011];

c := [ -0.88, -8.87, -0.86, -0.82, -0.77, -0.71, -0.66, -0.62, -0.57, -0.54, -0.89, -0.88, -0.85, -0.81, -0.76, -0.71, -0.66, -0.61, -0.57, -0.53]; 

 

Thanks in advance
