# MatSolverTypeRegister
Registers a `MatSolverType` that works for a particular matrix type 
## Synopsis
```
#include "petscmat.h" 
PetscErrorCode MatSolverTypeRegister(MatSolverType package, MatType mtype, MatFactorType ftype, PetscErrorCode (*createfactor)(Mat, MatFactorType, Mat *))
```

## Input Parameters

- ***package -*** name of the package, for example petsc or superlu
- ***mtype -*** the matrix type that works with this package
- ***ftype -*** the type of factorization supported by the package
- ***createfactor -*** routine that will create the factored matrix ready to be used
