Answer 1

This post在 Matlabs 网站上建议:

function comma2point_overwrite( 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;
    delete(file)
end
