% BITAND
%
% DEVELOPED TO SUPPORT BITWISE OPERATIONS WHEN PORTING C TO MATLAB
% 3-30-94
%
% ******************************************************************
%
% DESCRIPTION
%
% Compute bitwise AND (like C '&' operator) for two 8-bit integers
%
% DESIGN NOTES
%
% Uses 8-bit integer to binary forward/backward conversions, int2bin 
% and bin2int.
%
% SEE ALSO:  BIN2INT, INT2BIN
%
% VARIABLES
%
% INPUTS
%   a, b       -   Input integers (Actually double floats in MATLAB)
%                  These are truncated to 8 bits.
%
% OUTPUTS
%   aandb      -   Output integer result, a & b.
%
% ******************************************************************

function aandb = bitand( a, b )
aandb = bin2int( int2bin(a) & int2bin(b) );
