Details:

Octave seems to implement colormap() on the axis object while Matlab it is
tied to the figure. For example this works in Matlab


f=figure;
colormap(f,'cool')
get(f,'colormap')


while the following works in Octave, but returns the default colormap in later
Matlab versions


f=figure;
colormap(gca,'cool')
get(f,'colormap')
