Re: Reading text file data into matrices for selective plotting

surf(x,y,z) produces a blank graph and gives the following errors:

error: surface: rows (z) must be the same as length (y) and columns (z) must
be the same as length (x)
error: called from:
error: C:\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\plot\surface.m at line
111, column 9
error: C:\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\plot\surface.m at line
51, column 5
error: C:\Octave\3.2.4_gcc-4.4.0\share\octave\3.2.4\m\plot\surf.m at line
47, column 5

meshgrid(x,y,z) produces a large array of values that look like they might
have some connection to the original matrix but I am not entirely sure how.
