Bitwise AND.
z = lowdisc_bitand(x,y)
a m-by-n matrix of doubles, integer value, positive
a m-by-n matrix of doubles, integer value, positive
a m-by-n matrix of doubles, integer value, positive
Given x,y two positives integers this function returns the decimal number whose the binary form is the AND of the binary representations of x and y. If dimension of x (and y) is superior than 1 then z(i) is equal to bitand(x(i),y(i)).
