IMAGECF(Z)
IMAGECF(Z,Zmax)
IMAGECF(X+iY,Z)
IMAGECF(X+iY,Z,Zmax)
IMAGECF(ax,___)
IMAGECF(___, option) color of zero. 'w'-white 'k'-black
Example1>
[x,y] = meshgrid(-2:.1:2);
z = x + 1i*y;
imagecf(x+1i*y, z.^2+1,1,'k');
Example2> Mapping real 2D vector field
[x,y] = meshgrid(-2:.1:2);
vx = -y;
vy = x;
imagecf(x+1i*y, vx+1i*vy);
One may modify the code line 134-137 for colorset changes.
