ctprod

An array of dimension P_1 x ... x P_L x R_1 x ... x R_K.

An array of dimension R_1 x ... x R_K x Q_1 x ... x Q_M.

A positive integer, giving the number of modes to collapse.

Computes the contracted tensor product between two multiway arrays.

Functions to predict one multi-way array (i.e., a tensor) from another multi-way array, using a low-rank CANDECOMP/PARAFAC (CP) factorization and a ridge (L_2) penalty [Lock, EF (2018) <doi:10.1080/10618600.2017.1401544>]. Also includes functions to sample from the Bayesian posterior of a tensor-on-tensor model.
