Each multiplication requires a prefetch of y vector and x vector to fast memory. Depending on the inner loop i, A matrix lines are loaded to fast memory. dot_product(vector_a, vector_b) This function returns a scalar product of two input vectors, which must have the same length. 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, n) Se hela listan på wallstreetmojo.com A good example of an element by element matrix multiplication equation is the one used above of three models of cars that share three size motors of the same type. Element wise multiplication takes each column vector and row vector and multiplies them together to get the matrix vector product.

The Dot Product Definition of matrix-vector multiplication is the multiplication of two vectors applied in batch to the row of the matrix. Let M be an R x C matrix, M * u is the R-vector v such that v[r] is the dot-product of row r of M with u. $v = [\text{for each } r \in R: v[r] = (row_r \text{ of } M) * u]$
