Matrix-vector product. To define multiplication between a matrix A and a vector vcx (i.e. the matrix-vector product) we need to view the vector as a column In mathematics matrix multiplication or matrix product is a binary operation that produces a matrix from two matrices with entries in a field or more generally in a ring or even a semiring.Before defining matrix multiplication we need to introduce the concept of inner product of two vectors. Definition Let be a row vector and a column vector. Denote their entries by and by respectively.

I should start off by saying that if you are planning to do any serious work which requires vector mathematics you should probably just use one of the many open source libraries or packages

Dot_product(vector_a vector_b) This function returns a scalar product of two input vectors which must have the same graphicgth. matmul (matrix_a matrix_b) It returns the matrix product of two matrices which must be consistent i.e. have the dimensions like (m k) and (k nThis is the first of the two types of vector multiplication and it is called a scalar product because the result of the product is a scalar. We usually write the product
