inla.row.kron: Row-wise Kronecker products

Description Usage Arguments Value Author(s) See Also

View source: R/spde.common.R

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

1
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.
