Details:

Currently ind2rgb can only handle 2D images.  It'd be useful if it could
handle ND images (3D and 4D images are quite common in medical applications),
so I've attached a patch which enables this.  The changes I've made are to
ind2rgb.m and ind2x.m.

This will bring ind2rgb more into line with Matlab's behaviour, as it can also
handle ND images.  In fact, Matlab's ind2rgb (for R2010a anyway, I don't know
about later versions) only allows ND images to be handled if called with three
outputs:

[R,G,B] = ind2rgb(image,colormap);

...but I don't see any reason why it shouldn't also work with a single
output:

[R] = ind2rgb(image,colormap);

...so the attached patch works for ND arrays for both 1 and 3 outputs.

Adam
