Colormap with Image command

I'm trying to plot intensity levels from an 8-by-8 matrix A whose values vary from 0 to 1. As a start, I entered the following,
image(A);
colormap('autumn');
colorbar('EastOutside');
The result produces a colorbar whose values appear to increase from 0 to 60. I have no idea where the "60" is coming from. More problematic is that the entries of A are so small that I don't see any color variation in the image. It appears monochromatic. Of course, I can scale A by a large number, but this seems to mess up the colorbar values.
How can I change input into the image and/or colormap commands so as to see different colors? Of course, I can just multiply A by a large number, but this messes up the scaling on the colorbar. Also, I want the colorbar labels to increase from 0 to 1.
Any help would be appreciated.
