## 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
