isodd: a pedestrian parity checker

ISODD returns TRUE for integers of any numeric MATLAB class that are not evenly divisible by 2

Description

ISODD returns TRUE for members (N) of a numeric array, which
- are within the range of ±bitmax
- are integers such that N == fix(N)
- are integers not evenly divisible by 2

Unlike the typical computational approach using REM/MOD,
ISODD produces a not-valid flag for numbers, which are
1) not an integer
2) larger than the maximum possible double precision
   integer representation (±bitmax)
and does never return their parity as being odd

REM/MOD, on the other hand, do not complain if an input
is not a valid candidate for being even or odd at all
and, therefore, are NOT reliable parity checkers

• MATLAB release: MATLAB 7.8 (R2009a)
• Other requirements: works with any MATLAB versions that knows about the BIT-function family

Finally, a standard file which can be referenced for the perennial NG question! Well done. Thanks Urs.

Maybe you are the Herbert West re-animator of Brian Yuzna masterpieces. I hope is so! :))
