## Detailed Description

Base class for dense unsymmetric matrix systems of equations.

FullGenLinSOE is class which is used to store a full general system. The $$A$$ matrix is stored in a 1d double array with $$n*n$$ elements, where $$n$$ is the size of the system. $$A_{i,j}$$ is stored at location $$(i + j*(n)$$, where $$i$$ and $$j$$ range from $$0$$ to $$n-1$$, i.e. C notation. For example when $$n=3$$:

 [ {array}{ccc} a_{0,0} & a_{0,1} & a_{0,2} a_{1,0} & a_{1,1} & a_{1,2} a_{2,0} & a_{2,1} & a_{2,2} {array} ] 

is stored in:

 [ {array}{cccccccccccccccccccc} a_{0,0} & a_{1,0} & a_{2,0} & a_{0,1} & a_{1,1} & a_{2,1} & a_{0,2} & a_{1,2} & a_{2,2} {array} ] 

The $$x$$ and $$b$$ vectors are stored in 1d double arrays of length $$n$$. To allow the solvers access to this data, the solvers that use this class are all declared as friend classes.

## Member Function Documentation

 int XC::FullGenLinSOE::addA ( const Matrix & m, const ID & id, double fact = 1.0 )
virtual

Assembles the product of the matrix and the factor on the system matrix.

First tests that loc and M are of compatible sizes; if not a warning message is printed and a $$-1$$ is returned. The LinearSOE object then assembles fact times the Matrix {M} into the matrix $$A$$. The Matrix is assembled into $$A$$ at the locations given by the ID object loc, i.e. $$a_{loc(i),loc(j)} += //! fact * M(i,j)$$. If the location specified is outside the range, i.e. $$(-1,-1)$$ the corresponding entry in M is not added to $$A$$. If fact is equal to $$0.0$$ or $$1.0$$, more efficient steps are performed. Returns $$0$$.

Implements XC::LinearSOE.

## § setSize()

 int XC::FullGenLinSOE::setSize ( Graph & theGraph )
virtual

Computes the size of the system from the graph data.

The size of the system is determined by invoking getNumVertex() on theGraph. If the old space allocated for the 1d arrays is not big enough, it the old space is returned to the heap and new space is allocated from the heap. Prints a warning message, sets size to $$0$$ and returns a $$-1$$, if not enough memory is available on the heap for the 1d arrays. If memory is available, the components of the arrays are zeroed and $$A$$ is marked as being unfactored. If the system size has increased, new Vector objects for $$x$$ and $$b$$ using the {(double *,int)} Vector constructor are created. Finally, the result of invoking setSize() on the associated Solver object is returned.

Implements XC::LinearSOE.

## § setSolver()

 bool XC::FullGenLinSOE::setSolver ( LinearSOESolver * newSolver )
protectedvirtual

Checks if the solver has a suitable type and then it class its parent setSolver method.

Parameters
 newSolver solver to use.

Reimplemented from XC::LinearSOE.

## § zeroA()

 void XC::FullGenLinSOE::zeroA ( void )
virtual

Zeros the entries in the 1d array for $$A$$ and marks the system as not having been factored.

Implements XC::LinearSOE.
