5Matrix Product
Purpose 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.
This is equivalent to
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.
This is equivalent to
y = prod(u) % Equivalent MATLAB code
The output has the same frame status as the input.
