## @deftypefn {} {} dec2bin (@var{d}, @var{len})
## Return a binary number corresponding to the non-negative integer @var{d},
## as a string of ones and zeros.
##
## For example:
##
## @example
## @group
## dec2bin (14)
##      @result{} "1110"
## @end group
## @end example
##
## If @var{d} is a matrix or cell array, return a string matrix with one row
## per element in @var{d}, padded with leading zeros to the width of the
## largest value.
##
## The optional second argument, @var{len}, specifies the minimum number of
## digits in the result.
## @seealso{bin2dec, dec2base, dec2hex}
## @end deftypefn
