BandSPDLinSolver

A BandSPDLinLapackSolver object can be constructed to solve a BandSPDLinSOE object. It obtains the solution by making calls on the the LAPACK library. The class is defined to be a friend of the BandSPDLinSOE class (see \(<\)BandSPDLinSOE.h\(>\)).

// Constructor

// Destructor

// Public Methods

A unique class tag (defined in \(<\)classTags.h\(>\)) is passed to the BandSPDLinSolver constructor.

Does nothing.

The solver first copies the B vector into X and then solves the BandSPDLinSOE system by calling the LAPACK routines dpbsv(), if the system is marked as not having been factored, and dpbtrs() if system is marked as having been factored. If the solution is successfully obtained, i.e. the LAPACK routines return \(0\) in the INFO argument, it marks the system has having been factored and returns \(0\), otherwise it prints a warning message and returns INFO. The solve process changes \(A\) and \(X\).

Does nothing but return \(0\).

Does nothing but return \(0\).

Does nothing but return \(0\).
