Data fitting with Beta mixture models

I have data; one column and 310 rows. When I plot the histogram, it has two peaks; see the figure. I would like to use two mixed beta distribution for that. How can I do that? I know there is "Gaussian mixture model" in Matlab? Is there anything for mixture beta distributions?

Thank you

I don't know of any function explicitly designed for this special case, but you might be able to use nlinfit.
