## Name

dec2bin — binary representation

## Calling Sequence

[str]=dec2bin(x[,n])

## Parameters

- x
scalar/vector/matrix of positives integers

- n
a positive integer

- str
a string or a vector of string

## Description

Given `x`

, a positive (or a vector/matix 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 colums 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 componants 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), so 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)
