Visualize the depth matrix.

Hi,

I'm new in MATLAB. I have gained a "depth" matrix (700-by-700) from scanner, every element in the matrix represents the depth value (z-value) of each point.

How can I visualize this depth matrix? Do I need to use isosurface(x,y,z,v)? And if so, how to get the parameter "v"?

Thanks.

surf(z) % z - your  "depth" matrix

Thanks a lot for you answer. I knew surf, but I want to make it more beautiful using polygonal or volumetric visualization techniques. Could you advise me on this attempt?

If I understand it correctly you have the depth to the bottom surface, as a function of x and y. That is a type of data for which you won't need (and can't use) volumetric visualization. To need volumetric visualization you need to have at least scalar data as a function of (x,y,z) something like fog density, tissue X-ray absorption or the like.
