I have an MxN matrix, Z, and some variable h. This matrix represents the points to a solution of a function f(x,y). h is the spacing between points. For instance:
Z(x/h,y/h) = (some value in the Z direction), where x and y are some multiple of h
The domain is from 0 to M*h and the range is from 0 to N*h. I would like to make a 3d representation of the solution defined by the matrix. The graph should be similar to what is produced using the pdetool. How do I do this in Matlab?

plot3( X , Y , Z ) plots coordinates in 3-D space. To plot a set of coordinates connected by line segments, specify X , Y , and Z as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X , Y , or Z as a matrix and the others as vectors.
surf( X , Y , Z ) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors.
Description. plotmatrix( X , Y ) creates a matrix of subaxes containing scatter plots of the columns of X against the columns of Y . If X is p-by-n and Y is p-by-m, then plotmatrix produces an n-by-m matrix of subaxes.
You can use surf or bar3.
