n-Mode Tensor - Matrix Product

Calculates the n-mode product between a tensor and a matrix.

Description

according to the definition of De Lathauwer and as referenced by many papers.

B = A (x)_n U

((x)_n: is the multiplication operator, see screenshot!)

where:
  A: tensor of R^( I_1 × I_2 × .. I_n × .. I_N )
  U: matrix of R^( J × I_n)
  B: output tensor of R^(I_1 × I_2 × .. J × .. I_N)
  n: scalar within [1:N], specifying the mode

Syntax:
B = nmodeproduct(A, U, n)
