## @deftypefn {Function File} {} __bin2num__ (@var{b})
## Return the IEEE 754 double precision number represented by the binary number stored in the string @var{b}.  For example,
##
## @example
## __bin2num__ ("0011111111110000000000000000000000000000000000000000000000000000")
##      @result{} 1
## @end example
##
## If @var{b} is a string matrix, returns a column vector of converted numbers, one per row of @var{b}.
##
## @example
## __bin2num__ (["0011111111110000000000000000000000000000000000000000000000000000"; "1100000000001000000000000000000000000000000000000000000000000000"])
