How use interp2

I have:

• sigma which is a vector 1x6
• OMEGA which is a vector 1x10
• T which is a vector 6x10 (since T is a function of sigma e OMEGA).

I want to interpolate these functions in such a way on the x axis there is sigma, on the y axis there is OMEGA and on z axis there is T.

I also want to obtain a graph

Is it possible?

You can use interp2 like this

sigma = 1:6;
OMEGA = 1:10;
T = rand(6, 10);

interp2(sigma, OMEGA, T.', 4, 5) % (4,5) is a sample query point of format (sigma, omega). You can pass vectors too

How do you want to plot? contourf?

contourf(sigma, OMEGA, T.')
