Mix inputs (weighted addition).

In	Out	Description
`A_number`, `B_number`	`Y_number`	$Y=A.KA+B.KB$
`A_vector`, `B_vector`	`Y_vector`	$Y[i]=A[i].KA+B[i].KB$

with: 0 ≤ i < length of A_vector

The inputs KA and KB (mix/weighting factors) must be numbers.

-Compute the weight sum of inputs <var>A</var> and <var>B</var>.
-if <var>A</var> and <var>B</var> are numbers: <var>Y</var> = <var>A</var>.<var>KA</var> + <var>B</var>.<var>KB</var>
-if <var>A</var> and <var>B</var> are vectors: <var>Y</var>[i] = <var>A</var>[i].<var>KA</var> + <var>B</var>[i].<var>KB</var>
