dec2bin

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/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).
// 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)
