Memoryleak from memmapfile? Does it need to be deleted?

Hi I have a function like this:

function comma2point( filespec )
% replaces all occurences of comma (",") with point (".") in a text-file.
% Note that the file is overwritten, which is the price for high speed.
    file = memmapfile( filespec, 'writable', true );
    comma = uint8(',');
    point = uint8('.');
    file.Data( transpose( file.Data==comma) ) = point;
 end

I get memory problems sometimes and suspect this function. Do i need to delete the memmapfile manually? And in that case, how?

Thanks Erik

Noone?

You "suspect" this function. Could you please mention the arguments, what "memory problems" exactly mean and why you assume, that it depends on memmapfile? The OS and Matlab versions might be important also.

I'm not sure why you have the transpose() call in there ?
