Result value

The value of each element of the result is the result of a logical NOT operation of a logical OR operation between the corresponding elements of a and b.

Formula

d[0] = NOT (a[0] OR b[0])
d[1] = NOT (a[1] OR b[1])
d[2] = NOT (a[2] OR b[2])
d[3] = NOT (a[3] OR b[3])

Example

a =  (-1.0, -1.0,  1.0, 1.0)
b =  (-1.0,  1.0, -1.0, 1.0)
d: ( 1.0, -1.0, -1.0,-1.0)
