Try imhistmatch(), or for something more accurate, try the one in my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/28972-custom-shaped-histogram
For color, the best one I've seen is by Mark Grundland: http://www.eyemaginary.com/Portfolio/ColorHistogramWarp.html
Also see this by Brett Shoelson at the Mathworks: http://www.mathworks.com/matlabcentral/fileexchange/27396-matchhistograms

ABC's "Answer" moved here:
This is what I want. I need the code to generate the last graph in the image

Just make a line and clip it.
inputGrayLevels = 0 : 255;
outputGrayLevels = slope * (inputGrayLevels - centerGL);
% Clip
outputGrayLevels = max(outputGrayLevels, 0);
outputGrayLevels = min(outputGrayLevels, 255);
