How to fit multiple peaks using Gaussian funtion

I am trying to fit my XRD pattern using Gaussian function. I have a dominant peak and several small peaks. I have 'angel' as x-axis, and 'Intensity' as y-axis. I applied : f=fit(angel, Intensity,'gauss2'); plot(f,angel, Intensity);
But it will only fit my dominate peak. Could you please let me know how to fit the rest of the small peaks?
Besides, I also want to report the area (integration) of each peak, how should I achieve that?
Thanks a lot!

Never noticed the original of this question, but saw the comment.
If you have the Statistics and Machine Learning Toolbox, I believe the fitgmdist function will be helpful for this.
