How to do a contour plot of a matrix C with respect to matrices A and B as X and Y axis?

I have three matrices A,B and C having same size 40*40. I want to plot a contour of C(40*40) taking A(40*40) as x axis and B(40*40) as y axis. Is it the correct way to plot by the following code ? Please help.

contourf (A,B,C);

A and B need to be monotonically increasing grids as would be the result from meshgrid

[xx,yy] = meshgrid(linspace(0,1,40));
contour(xx,yy,magic(40))

please explain in terms of A,B and C...A B, and C has the values in the ranges 0-30, 200-900 and 0.1-0.9 respectively.

Read the documentation for meshgrid and contour.

I have read the documentation...but still not able to do it.....
