khatri_rao-methods {DelayedTensor} | R Documentation

## 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.

### Examples

    library("DelayedRandomArray")
    darr1 <- RandomUnifArray(c(2,4))
    darr2 <- RandomUnifArray(c(3,4))
    khatri_rao(darr1, darr2)
