filesize - return a file's size in bytes FORMAT: fsz = filesize(filename) Input fields: filename filename Output fields: fsz filesize Note: returns NaN if the file doesn't exist
This function uses Matlab's internal
dir function instead of reading the file. This means that this number is only valid for files that are not in use when written to. In some cases the filesystem reports an incorrect size (e.g. some operating systems report a size of 0 for files that have not been flushed yet while they are written)!
