Multiply the elements of a matrix along rows or columns.
Library
Math Functions / Matrices and Linear Algebra / Matrix Operations
Description
The Matrix Product block multiplies the elements of an M-by-N input matrix u along either the rows or columns.
When the Multiply along parameter is set to Rows, the block multiplies across the elements of each row and outputs the resulting M-by-1 matrix. A length-N 1-D vector input is treated as a 1-by-N matrix.
y = prod(u,2) % Equivalent MATLAB code
When the Multiply along parameter is set to Columns, the block multiplies down the elements of each column and outputs the resulting 1-by-N matrix. A length-M 1-D vector input is treated as a M-by-1 matrix.
y = prod(u) % Equivalent MATLAB code
The output has the same frame status as the input.
