Does this actually work? With a recent CVS checkout I get the following
behaviour:
* "imshow(rand(100))" shows a color image, while it should be a
gray-scale image (rand(100) is 2D and hence gray-scale).
Display the image IM, where IM can a 2-dimensional (gray-scale
image) or a 3-dimensional (RGB image) matrix. If three matrices of
the same size are given as arguments, they will be concatenated
into a 3-dimensional (RGB image) matrix.
In a hurry to document, someone may have typed "gray-scale" when really what was meant is
gradient or "according to colormap".
However, there may be a bug somewhere. I'd think that
colormap(gray(64));
imshow(rand(100));
would be gray-scale, but that too has a color gradient.
* "I(:,:,3) = rand(100); imshow(I)" shows a horizontal gradient image
where the left-most color is black, going through, purple to red, ending
in the right-most color being yellow. The shown image should have been a
blue image containing random values.
Definitely a bug there.
