Computes the min and max values within the input array, convert to 256 values, and apply a colormap to produce a color image (RGB).

It is possible to specifies the range of values to consider, as well as the background color (used for NaN values).

Example:
% Display a default matrix
subplot(1, 2, 1);
imshow(peaks(128), []);
title('as double')
% display the coresponding RGB image
subplot(1, 2, 2); imshow(double2rgb(peaks(128), jet, [-8 8]));
title('as RGB');
