That's what my File Exchange submission does: Custom shaped histogram

You can adjust the image to produce whatever profile you want for a histogram, like three Gaussian humps or whatever.

If you want to take an array (like a 1-D array of histogram counts) and fit it to Gaussian analytical formulas, you can use fitnlm() in the stats toolbox. See attached demos. Just download and click Run and they should work. They each do something slightly different.
