int2strz.m

This is a really simple program that makes the same as int2str but pads with zeros those integers with less digits than the maximum one.
It is useful (I hope) when our program reads files with names like: xxx001.dat, xxx002.dat, ..., xxx099.dat, xxx100.dat, etc., and we don't want to make use of if's to put zeros to int2str outputs (great isn't it).

int2strz(X,N) pads up to N digits (see the screenshot).
