>> x=-6:0.001:6; >> y=-6:0.001:6; >> [X,Y]=meshgrid(x,y); >> phi=x.*y-y; >> contour(x,y,phi) Error using contour (line 48) Z must be at least a 2x2 matrix.

EDITED
x=linspace(-6,6,1000);
y=x;
[X,Y]=meshgrid(x,y)
phi=X.*Y-Y
contour(X,Y,phi)

Matlab froze when I typed this in, it hasn't worked yet.

Not yet, but I think its an issue with my computer running Matlab, not the code. Thanks.
