I have a general question about memory management of functions in Matlab.

As far as I know, once the Matlab quits a function, all the memory allocated for that particular function is deallocated from memory.

I have created the following code

while true

a=CalValues;

end

Here is the CalVaues function

%-----

function a=CalValues

a=datestr(now,'yyyymmddHHMMSS');

end

So, basically I am continuously calling a function (a=CalValues) inside a while-loop. After one hour of continuous running the script, I realized that the memory allocated for Matlab is increasing continuously too.

When I break the while-loop with Ctrl+C, then the memory is deallocated. I was wondering Why the memory keep growing in RAM? There is nothing else inside the while-loop.

Is it possible that the Memory is not been deallocated if you call a function inside a while-loop? or till you are really outside of while-loop?

Thanks, Yavyuz
