Detailed Description
A FullGenLinLapackSolver object can be constructed to solve a FullGenLinSOE object. It obtains the solution by making calls on the the LAPACK library. The class is defined to be a friend of the FullGenLinSOE class (see 
FullGenLinSOE.h\form#24). \
{\bf Interface} \ Constructor \ {FullGenLinLapackSolver();} \ \ Destructor \ {\form#25FullGenLinLapackSolver();}\\ \ 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} \ {FullGenLinLapackSolver();} \ A unique class tag (defined in
classTags.h\form#24) is passed to the FullGenLinSolver constructor. Sets the size of {iPiv} to 
, {iPiv} being an integer array needed by the LAPACK routines. \
{\bf Destructor} \ {\form#25FullGenLinLapackSolver();}\\ Invokes delete on {iPiv} to free the memory it was allocated. \
{\bf Public Methods } \ {int solve(void);} \ First copies 
into 
and then solves the FullGenLinSOE system it is associated with (pointer kept by parent class) by calling the LAPACK routines {dgesv()}, if the system is marked as not having been factored, or {dgetrs()}, 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
