WebAccording to the definition of outer product, the outer product of A and B should be a 2 × 2 × 2 × 3 tensor. You can follow this answer to compute it using numpy. This is a valid point. One should be careful with the term "outer product" since it … Webexample. B = prod (A) returns the product of the array elements of A. If A is a vector, then prod (A) returns the product of the elements. 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. If A is an empty 0-by-0 matrix, prod (A) returns 1.
