Hey everyone. I'm having some trouble with getting the contour lines in a simple "v" vector to plot. Below is the code I'm using. Instead of following the values in v, meshc just throws it out and plots the default points. Also, the function is not plotted above these default contour lines. What is incorrect?

[x y] = meshgrid(-1:1,-1:1);
z=((y-x).^4) + (12*x*y) - x + y - 3;
v=sort([1.3765 -4.7342 0.3484]);
meshc(x,y,z,v)

Thanks for your help!
