Description
Block Dot Product Calculates the scalar product of the input vectors. The scalar output of is equal to:
,
where and are input vectors.
The input signal can be a vector, a column vector (a matrix with one column), or a scalar. If both inputs are vectors or column vectors, they must be of the same length. If and are both column vectors, the block outputs the equivalent of the expression .
The elements of the input vectors can be real or complex signals. The type of signal (complex or real) at the output depends on the types of signals at the inputs.
