Functions

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

Function Documentation

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:
aDense matrix a
bDense matrix b
Returns:
Kronecker tensor product of a and b
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:
aDense/sparse matrix a
bDense/sparse matrix b
Returns:
Kronecker tensor product of a and b, stored in a sparse matrix
