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 vector.

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 vector.

This is equivalent to

y = prod(u)          % equivalent MATLAB code

Dialog Box

Multiply along: The dimension of the matrix along which to multiply, row or column.
Number of columns in input: The number of columns in the input matrix.
