I get a different error when I try to run your code, but I don't think
that matters. You are not sending persp(), x's and y's that meet its
requirements. See the help file for persp:
"Arguments
x, y locations of grid lines at which the values in z are
measured. These must be in ascending order. "
I do not think you have z's for each of your (x,y) pairs. And your
values are not increasing.
