Details:

I wanted to start with the code sprint, adding a demo for surfc and found the
following issue with surfc.

octave:6> [X,Y,Z] = sombrero;
octave:7> [fx,fy] = gradient(Z);
octave:8> surfc(X,Y,Z,fx+fy)
warning: implicit conversion from real matrix to real scalar
warning: implicit conversion from real matrix to real scalar

After that octave hangs and I have to press CTRL+C

Maybe I have time to fix this later today.

Kai
