prod

Product of array elements

Syntax

Description

B = prod(A) returns the products along different dimensions of an array.

If A is a vector, prod(A) returns the product of the elements.

If A is a matrix, prod(A) treats the columns of A as vectors, returning a row vector of the products of each column.

If A is a multidimensional array, prod(A) treats the values along the first non-singleton dimension as vectors, returning an array of row vectors.

B = prod(A,dim) takes the products along the dimension of A specified by scalar dim.

Examples

The product of the elements in each column is

The product of the elements in each row can be obtained by:
