ttm: Tensor times matrix

In tensorr: Sparse Tensors in R

Description

Calculates the n-mode product of a tensor and a matrix. Given a tensor X with dimensions I_1, I_2, ..., I_n, I_n+1, ... I_N and a matrix U with dimensions J, I_n, the resulting tensor after multiplication will have dimension I_1, I_2, ..., J, I_n+1, ... I_N.

Usage

ttm(x, u, mode)

## S4 method for signature 'dtensor,Matrix,numeric'
ttm(x, u, mode)

## S4 method for signature 'dtensor,matrix,numeric'
ttm(x, u, mode)

## S4 method for signature 'sptensor,Matrix,numeric'
ttm(x, u, mode)

## S4 method for signature 'sptensor,matrix,numeric'
ttm(x, u, mode)

Arguments

x	tensor
u	matrix
mode	mode along tensor to perform multiplication
