Plotting 3-D Matrix *values* in MATLAB

I have a 3D Matrix M(256x256x136) and each index(i,j,k) in M has a gray level value in it. I am interested in displaying M in some sort of a 3D plot in MATLAB, but am unable to do so. I cannot use plot3 because plot3 is for plotting points, not the values.

Thanks

If I understand your question correctly, you want to plot the 3D point cloud with i,j, and k as 3D coordinates and the gray level as the point value.

I would suggest using scatter3.

Sounds like you are looking for a volume renderer. For Matlab, you could try this one: Volume Render from Matlab Central

An isosurface plot might be useful as well.
