KroneckerProduct module

Detailed Description

This module contains an experimental Kronecker product implementation.

* #include <Eigen/KroneckerProduct>
* 

Functions
template<typename A , typename B >
KroneckerProduct< A, B >	kroneckerProduct (const MatrixBase< A > &a, const MatrixBase< B > &b)
template<typename A , typename B >
KroneckerProductSparse< A, B >	kroneckerProduct (const EigenBase< A > &a, const EigenBase< B > &b)

Function Documentation

KroneckerProduct<A,B> Eigen::kroneckerProduct	(	const MatrixBase< A > &	a,
		const MatrixBase< B > &	b
	)

Computes Kronecker tensor product of two dense matrices

Warning

If you want to replace a matrix by its Kronecker product with some matrix, do NOT do this:

* A = kroneckerProduct(A,B); // bug!!! caused by aliasing effect
* 

instead, use eval() to work around this:

* A = kroneckerProduct(A,B).eval();
* 

Parameters

a	Dense matrix a
b	Dense matrix b

Returns

Kronecker tensor product of a and b

KroneckerProductSparse<A,B> Eigen::kroneckerProduct	(	const EigenBase< A > &	a,
		const EigenBase< B > &	b
	)

Computes Kronecker tensor product of two matrices, at least one of which is sparse

Parameters

a	Dense/sparse matrix a
b	Dense/sparse matrix b

Returns

Kronecker tensor product of a and b, stored in a sparse matrix
