khatri_rao: Khatri-Rao Product

In rTensor: Tools for Tensor Analysis and Decomposition

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(x, y)

Arguments

x	first matrix
y	second matrix

Value

matrix that is the Khatri-Rao product

Note

The number of columns must match in the two inputs.

Examples

dim(khatri_rao(matrix(runif(12),ncol=4),matrix(runif(12),ncol=4)))

Example output

[1] 9 4
