Hello, Quick question : is it possible to make surfc works with vectors ? I have 4 vectors (x,y,z & c for the color) of the same length (1 point per quadruple xyzc ) but I don't understand how to turn them into matrix as surfc asks me. The xyz points are uniformly spaced. Any idea ?

Use reshape function, or interpolate the data:

Matrices can be any size, but you need to know it.
[x,y] = meshgrid(-2:.1:2, -2:.2:2);
x = x(:);
y = y(:);
z = x.*exp(-x.^2 - y.^2);
c = abs(z);
surfc(reshape(x,21,41),reshape(y,21,41),reshape(z,21,41),reshape(c,21,41))
