Detailed Description
Lapack based full (dense) general matrix SOE solver.
Solver for 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.
Member Function Documentation
§ setSize()
|
virtual |
Sets the size of #iPiv from the size of the system of equations.
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 resizes it. Returns 0 if sucessfull, prints a warning message and returns a -1 if not enough memory is available for this new array.
Implements XC::LinearSOESolver.
§ solve()
|
virtual |
Computes the solution.
First copies B into X 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 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.
Implements XC::Solver.
