gsKroneckerOp< T > Class Template Reference

Detailed Description

template<class T>
class gismo::gsKroneckerOp< T >

Class for representing a Kronecker product of operators of type gsLinearOperator.

\( op = op_0 \otimes op_1 \otimes \cdots \otimes op_{n-1} \)

where \( A \otimes B = ( a_{11} B \ a_{12} B \ ... ; a_{21} B \ a_{22} B \ ... ; ... ) \).
