int2vec

Convert integer to vector.

Description

Useful when you want to interpret integers as codewords.It also could be used to convert the output of the binary representation of an integer to vector.

Function call v=int2vec(s,l)
 s is the integer to be converted.
 l is the length of the integer in bits. For example v=int2vec(110,3)
 returns v=[1 1 0].

• MATLAB release: MATLAB 7 (R14)

The following fast one-liner will produce the same result:
sprintf(sprintf('%%0%id',LEN),INT)-'0'
in which LEN is the length and INT is the integer. There many other vectorized ways as well.
And what if the input is 120 ??

[Jim Simos]

It certainly needs improvement.
Btw,your suggestion fails from 11 bits. :)

>> vec=sprintf(sprintf('%%0%id',11),12345678912)-'0'

vec =

     1 -2 2 3 4 5 6 8 53 -5 0 1 0

Btw,your suggestion fails from 11 bits...
...because jos really meant to say

num=1234567890123456;
len=20;
v=sprintf(sprintf('%%0%d.f',len),num)-'0'

Good,enough.More convenient to use than the sprintf command.

[Tao Xia]

Good,but simple

[Jos Wiley]

Excellent!Helped me a lot.Thanks.

[Valtteri Ervasti]

Thank you! Just what I needed.

[Andrea Svirkokakhova]

Very helpful!

[evgeni evshenko]

what about
str2num((num2str(n)'))'
where n is any integer?
