R: Row-wise Kronecker products

inla.row.kron {INLA}

R Documentation

Row-wise Kronecker products

Description

Takes two Matrices and computes the row-wise Kronecker product. Optionally applies row-wise weights and/or applies an additional 0/1 row-wise Kronecker matrix product, as needed by inla.spde.make.A().

Usage

inla.row.kron(M1, M2, repl = NULL, n.repl = NULL, weights = NULL)

Arguments

`M1`	A matrix that can be transformed into a sparse Matrix.
`M2`	A matrix that can be transformed into a sparse Matrix.
`repl`	An optional index vector. For each entry, specifies which replicate the row belongs to, in the sense used in `inla.spde.make.A()`.
`n.repl`	The maximum replicate index, in the sense used in `inla.spde.make.A()`.
`weights`	Optional scaling weights to be applied row-wise to the resulting matrix.

Value

A sparseMatrix object.
