DEC2BIN Convert Decimal to Binary String

Section: Type Conversion Functions

USAGE

Converts an integer to a binary string. The syntax for its use is 
   y = dec2bin(x,n)

where x is the positive integer, and n is the number of bits to use in the representation. Alternately, if you leave n unspecified, 

   y = dec2bin(x)

the minimum number of bits needed to represent x are used. If x is a vector, then the resulting y is a character matrix.

Example

Here we convert some numbers to bits 
--> dec2bin(56)

ans = 
111000
--> dec2bin(1039456)

ans = 
11111101110001100000
--> dec2bin([63,73,32],5)

ans = 
11111
01001
00000
