prod

Product of array elements.

Syntax

B = prod(A)
B = prod(A, dim)

Description

Returns the product of A’s elements. With no dimension argument, multiplies along the first non-singleton dimension. With dim, multiplies along that dimension. NaN values cause the product to be NaN.

Examples

prod([1 2 3 4])             % 24
prod([1 2; 3 4])            % [3 8]   column products
prod([1 2; 3 4], 2)         % [2; 12] row products
