Function Documentation

kroneckerProduct() [1/2]

template<typename A, typename 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

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/sparse matrix a
b	Dense/sparse matrix b

Returns

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

kroneckerProduct() [2/2]

template<typename A, typename B>

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
