dec2bin

Arguments

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)
