int2strz.m

Same as int2str but with zero padding to the left.

Description

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).

Did you look at the documentation ?

X=[0 1 11 111]'

num2str(X,'%05d')
% or
sprintf('%05d',X')

IMHO, you should remove this submission.

Sorry, should read :

sprintf('%05d\n',X)

Yes jerome, but for us that doesn't like or want to write or read or simply don't understand thinks like '%..d', this is a beauty option and more readable. Question: why you don't complain about the int2str(x) function? We can do the same with num2str(round(x)) don't you think???
