Fit A Curve to a Histogram

Hisgram distribution

Is there any possibility to fit a curve to that histogram above in Matlab?

The histogram is not normalized or anything like that. I know that there is a function called histfit,but can i use it here?

Solution

Try this FileExchange submission:

ALLFITDIST - Fit all valid parametric probability distributions to data.

--- UPDATE ---

ALLFITDIST is no longer available on the MATLAB File Exchange.

You can try this instead:

FITMETHIS - finds best-fitting distribution to data vector, including non-parametric.
