mtimes

Vector-vector multiplication (dot product).

Slice!(Contiguous, [2], BlasType!(IteratorA, IteratorB)*) mtimes(Slice!(kindA, [2], IteratorA) a, Slice!(kindB, [2], IteratorB) b)
Slice!(Contiguous, [1], BlasType!(IteratorA, IteratorB)*) mtimes(Slice!(kindA, [2], IteratorA) a, Slice!(kindB, [1], IteratorB) b)
Slice!(Contiguous, [1], BlasType!(IteratorA, IteratorB)*) mtimes(Slice!(kindB, [1], IteratorB) a, Slice!(kindA, [2], IteratorA) b)
CommonType!(BlasType!IteratorA, BlasType!IteratorB) mtimes(Slice!(kindB, [1], IteratorB) a, Slice!(kindA, [1], IteratorA) b)
CommonType!(BlasType!IteratorA, BlasType!IteratorB)

(
SliceKind kindA

SliceKind kindB

)
(
Slice!(kindB, [1], IteratorB) a
,
Slice!(kindA, [1], IteratorA) b
)

Parameters

a Slice!(kindB, [1], IteratorB): 1(rows) x k(cols) vector
b Slice!(kindA, [1], IteratorA): k(rows) x 1(cols) matrix Result: scalar

Examples

auto a = [1, 2, 4].sliced;
auto b = [3, 4, 2].sliced;
assert(a.mtimes(b) == 19);
