Hello all,
Just wondering if its possible to modify the colourmap, to have it using the gray scale, but have the range of colours between 0 and 1, i.e. 0 being white and 1 being black, or vice versa.
if so, how?
Thanks!

Just flip the colormap.
figure
peaks
colorbar
colormap gray % effectively equivalent, due to how colormap works, to colormap(gray)
title('Normal')
figure
peaks
colorbar
colormap(flip(gray))
title('Flipped')
