Hello,
could anyone advise me how to make a cylinder from 2D matrix of a number of rows and columns eg x = rand(5,10). And then interpolate values around its perimeter and display it?
Best regards

If you have the Image Processing Toolbox, you would use the warp command, e.g.,
[X,Y,Z] = cylinder(ones(1,5),100);
warp(X,Y,Z,rand(5,10));

Can't you just call colormap and specify the desired colormap?
colormap(jet)
