Is fmincon open source

I can check fmincon.m in Matlab, I can also find description of the code in Matlab. I was wondering if the full of the code behind this function is available to public or not? If not, what part is not revealed? Thank you very much! And how about the benchmark of fmincon vs some popular open source optimization softwares?

If you can open the file then you can probably read the copyright, which looks something like this:
