Problem 44258. Outer product of multiple vectors

Created by Andrew Newell

Solve Later

In tensor algebra, it is often useful to define a tensor as a product of lower order tensors. Similarly, a multidimensional array T might be defined as an outer product of vectors, where a given element is defined by

T(i,j,k) = A(i)*B(j)*C(k);

Create a function outerProduct that accepts any number of row or column vectors and calculates their outer product. For the above example,

T = outerProduct(A,B,C);

The final test may not be the ideal choice, as the answer, with expected value around 50¹⁰⁰⁰ ~ 10¹⁶⁹⁹, becomes "Inf" almost certainly. Also there are no outputs of dimension>2 required by the Test Suite.
