# dec2bin

convert from decimal to binary

### Syntax

```str=dec2bin(x)
str=dec2bin(x,n)```

### Arguments

x

matrix of doubles, positive integer values

n

a positive integer

str

a matrix of strings

### Description

Given `x`, a positive (or a vector/matrix of integers) integer, this function returns a string (or a column vector of strings) which is the binary representation of `x.`If dimension of `x` is superior than 1 then each component of the column vector `str` is the binary representation of the `x` components (i.e `str(i)` is the binary representation of `x(i)`).

If the components length of `str` is less than `n` ( i.e length str(i) < n ), then add to `str` components the characters '0' on the left in order to have components length equal to `n.`

### Examples

```// example 1 :
x=86;
str=dec2bin(x)

// example 2 :
// The binary representation of 86 is: '1010110'.
// Its length is 7 (less than n).
// We add to str 8 times the character '0' (on the left).
x=86;
n=15;
str=dec2bin(x,n)

// example 3 :
x=[12;45;135]
z=dec2bin(x)```
