Gaussian Distribution fit to Known Data?

Hey all. I'm trying to make a Gaussian curve fit to a histogram made with data I already have. It is not normalized and I do not know anything about the curve other than what data it needs to fit. What function in MATLAB can I use to calculate sigma and mu? Thanks for your help.

If you have the Statistics Toolbox, you can use normfit().

Where do I get the Statistics Toolbox? I'm using a student edition of MATLAB. Do I have to download it from somewhere?

According to this page, the student version comes with the Statistics Toolbox. If you type

ver

at the command line, you should see it listed.

Type

doc normfit

to see the syntax for the normfit() command.
