Detailed Description

Iterative Solvers supporting block recursive matrix and vector classes at compile time.

The Iterative Solver Template Library applies generic programming in C++ to the domain of iterative solvers of linear systems stemming from finite element discretizations. Those discretizations exhibit a lot of structure, e.g:

Certain discretizations for systems of PDEs or higher order methods result in matrices where individual entries are replaced by small blocks, say of size $2\times 2$ or $4\times 4$ . Dense blocks of different sizes e.g. arise in Discontinuous Galerkin discretization methods. It is straightforward and efficient to treat these small dense blocks as fully coupled and solve them with direct methods within the iterative method.
Equation-wise ordering for systems results in matrices having an $n\times n$ block structure where corresponds to the number of variables in the PDE and the blocks themselves are large and sparse. As an example we mention the Stokes system.
Other discretisation, e.~g. those of reaction/diffusion systems, produce sparse matrices whose blocks are sparse matrices of small dense blocks,

Our matrix and vector interface supports a block recursive structure. Each sparse matrix entry can itself be either a sparse or a small dense matrix.

The solvers use this recursive block structure via template meta programming at compile time.

ISTL consists of the matrix and vector API and the solvers which use the Preconditioners preconditioners.

explicit

Constructs the SuperLU solver.

During the construction the matrix will be decomposed. That means that in each apply call forward and backward substitutions take place (and no decomposition).

Parameters

mat	The matrix of the system to solve.
verbose	If true some statistics are printed.
reusevector	Default value is true. If true the two vectors are allocate in the first call to apply. These get resused in subsequent calls to apply and are deallocated in the destructor. If false these vectors are allocated at the beginning and deallocated at the end of each apply method. This allows using the same instance of superlu from different threads.

Try loading a decomposition from file and do a decomposition if unsuccessful.

Parameters

mat_	the matrix to decompose when no decoposition file found
file	the decomposition file

Use saveDecomposition(char* file) for manually storing a decomposition. This constructor will decompose mat_ and store the result to file if no file wasn't found in the first place. Thus, if you always use this you will only compute the decomposition once (and when you manually deleted the decomposition file).
