khatri_rao: Khatri-Rao Product of DelayedArray

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

Khatri-Rao Product of DelayedArray

Description

Returns the Khatri-Rao (column-wise Kronecker) product of two matrices. If the inputs are vectors then this is the same as the Kronecker product.

Usage

khatri_rao(darr1, darr2)

## S4 method for signature 'DelayedArray,DelayedArray'
khatri_rao(darr1, darr2)

Arguments

darr1	first DelayedArray object
darr2	second DelayedArray object

Details

This function is an extension of the khatri_rao by DelayedArray.

Value

matrix that is the Khatri-Rao product

Note

The number of columns must match in the two inputs.
