Help on imagesc

Hello all,

I need to plot a matrix X using imagesc.

>> imagesc(v,f,X);

However, each column of X is described by a different f, but imagesc will not let me use a matrix there.

Any ideas how can I plot X using the corresponding f for each column?

Thanks a lot,

imagesc() and image() require rectangular grids. You will have to construct your own plot using patch(), possibly with texture mapping.

Would please provide additional details? Patch works but renders an incomprehensible figure.
