In rikenbit/DelayedTensor: R package for sparse and out-of-core arithmetic and decomposition of Tensor

Khatri-Rao Product against list

Description

Returns the Khatri-Rao product from a list of matrices or vectors. Commonly used for n-mode products and various Tensor decompositions.

Usage

khatri_rao_list(L, reverse = FALSE)

Arguments

L	list of DelayedArray
reverse	whether or not to reverse the order

Details

This function is an extension of the khatri_rao_list by DelayedArray.

Value

matrix that is the Khatri-Rao product

Note

The number of columns must match in every element of the input list.
