Detailed Description
A BandGenLinLapackSolver object can be constructed to solve a BandGenLinSOE object. It obtains the solution by making calls on the the LAPACK library. The class is defined to be a friend of the BandGenLinSOE class (see 
BandGenLinSOE.h\form#24). \
{\bf Interface} \ Constructor \ {BandGenLinLapackSolver();} \ \ Destructor \ {\form#25BandGenLinLapackSolver();}\\ \ Public Methods \ {int solve(void);} \ {int setSize(void);} \ {int sendSelf(int commitTag, Channel &theChannel);} \ {int recvSelf(int commitTag, Channel &theChannel, FEM\_ObjectBroker &theBroker);} \
{\bf Constructor} \ {BandGenLinLapackSolver();} \ A unique class tag (defined in
classTags.h\form#24) is passed to the BandGenLinSolver constructor. Sets the size of {iPiv} to 
, {iPiv} being an integer array needed by the LAPACK routines. \
{\bf Destructor} \ {\form#25BandGenLinLapackSolver();}\\ Invokes delete on {iPiv} to free the memory allocated to store the array. \
{\bf Public Methods } \ {virtual int solve(void);} \ The solver first copies the B vector into X and then solves the BandGenLinSOE system by calling the LAPACK routines {dgbsv()}, if the system is marked as not having been factored, and {dgbtrs()} if system is marked as having been factored. If the solution is successfully obtained, i.e. the LAPACK routines return
in the INFO argument, it marks the system has having been factored and returns
, otherwise it prints a warning message and returns INFO. The solve process changes 
and 
. \
{int setSize(void);} \ Is used to construct a 1d integer array, {iPiv} that is needed by the LAPACK solvers. It checks to see if current size of {iPiv} is large enough, if not it deletes the cold and creates a larger array. Returns
if sucessfull, prints a warning message and returns a 
if not enough memory is available for this new array. \
{int sendSelf(int commitTag, Channel &theChannel);} \ Does nothing but return
. \
{int recvSelf(int commitTag, Channel &theChannel, FEM\_ObjectBroker &theBroker);} \ Does nothing but return
. \
