Detailed Description

template<typename T_Matrix>
class culite::LapackLU< T_Matrix >

The partial pivoting LU linear solver for dense device matrices.

Implements the LU decomposition with partial pivoting \( P A = L U \) for general matrices stored in device memory. This is the GPU version using cuSOLVER.

Template Parameters

T_Matrix

The device matrix type (e.g., dns::XxMatrix<T_Scalar>).

Examples

ex05a_solving_linear_systems_lu.cpp.

Constructor & Destructor Documentation

LapackLU()

template<typename T_Matrix>

culite::LapackLU< T_Matrix >::LapackLU ( CuSolverHandler & cusolver = globalCuSolverHandler() )

inline

Constructor.

Initializes the LU solver with the specified cuSOLVER handler.

Parameters

[in]

cusolver

Reference to the cuSOLVER handler (defaults to global handler).

~LapackLU()

template<typename T_Matrix>

culite::LapackLU< T_Matrix >::~LapackLU ( )

default

Destructor.

Destroys the solver and releases allocated resources.
