Requires:
Each of these operators may only be instantiated for a type
T
to which the indicated operator can be applied and for which
the indicated operator returns a value which is of type
bool
or which can be unambiguously implicitly converted to type
bool. The two array arguments have the same length
.Returns:
A
valarray<bool> whose length
is equal to the length of the array arguments
. Each element of the returned
array is initialized with the result of applying the indicated
operator to the corresponding elements of the argument arrays
