Modifying colourmap to suit needs

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')
