R Documentation

Iterated Kronecker product

Description

Compute the Kronecker product of several matrices.

Usage

kprod(..., FUN = `*`)

Arguments

`...`	A listing of matrices
`FUN`	A function to pass to `kronecker()`

Details

If kronecker is the function that computes A x B, kprod computes A x B x C and so on; it's a wrapper of Reduce and kronecker.

Value

A matrix that is the kronecker product of the specified matrices (from left to right).

Examples


kprod(diag(2), t(ones(2)))
kprod(t(ones(2)), diag(2))


kprod(diag(2), t(ones(2)), t(ones(2)))
kprod(t(ones(2)), diag(2), t(ones(2)))
kprod(t(ones(2)), t(ones(2)), diag(2))


# cf. aoki, hara, and takemura p.13
rbind(
  kprod(diag(2), t(ones(2))),
  kprod(t(ones(2)), diag(2))
)
