Follow-up Comment #2, bug #40664 (project octave):
I agree that rgb2ind is wrong and needs to be updated to be consistent with
ind2rgb. However, I disagree with the changes that would make it work with
ndims > 4.
I'm well familiar with images that have that many dimensions (mine are
microscopy images with multiple channels, time and z-slices) but there is no
definition about which dimension each belongs to. At the end, they're all 2D
images. The third dimension is for color, and the 4th just stacks the images
together. The 4th dimension of the matrix is not meant to represent a 3D
image, it's to just group many 2D images into one matrix.
