Only element-by-element operations are defined on N-D arrays. As
far as I understand, other operations (such a *) first convert the
tensor to a matrix. However, somo built-in functions operate natively
on N-D arrays, for example fftn, ifftn, convn.
If you want to operate more generally on tensors, you may try this
package (I never did):
