How do I draw an histogram knowing the frequency of all the individual elements in a 150x150 matrix appears using matlab?

Please don't ask the same question a third time. That you still don't undertand what to do just means you need to prompt one of the many people who have already answered these duplicate questions for followup.

Given that my answer has already been provided, I see no reason to keep it or to keep this thread. Other mods are welcome to tidy up the others, but I'm just going to close this one.

See histogram() and histcounts()

A = randn(150,150); % normally distributed random numbers
histogram(A) % looks like a gaussian to me

There are many different options, but I'm just using defaults here. If you have specific bin edges or a preferred method of calculating bin locations, see the documentation for details on how to set that up.
