How do you multiply all elements in an array in Matlab?

B = prod( A ) returns the product of the array elements of A .

1. If A is a vector, then prod(A) returns the product of the elements.
2. If A is a nonempty matrix, then prod(A) treats the columns of A as vectors and returns a row vector of the products of each column.
3. If A is an empty 0-by-0 matrix, prod(A) returns 1 .
