# MatMkl_CPardisoSetCntl
Set Mkl_Pardiso parameters 
## Synopsis
```
#include "petscmat.h"  
PetscErrorCode MatMkl_CPardisoSetCntl(Mat F, PetscInt icntl, PetscInt ival)
```
Logically Collective


## Input Parameters

- ***F -*** the factored matrix obtained by calling `MatGetFactor()`
- ***icntl -*** index of Mkl_Pardiso parameter
- ***ival -*** value of Mkl_Pardiso parameter



## Options Database Key

- ***-mat_mkl_cpardiso_<icntl> <ival> -*** set the option numbered icntl to ival





## Note
This routine cannot be used if you are solving the linear system with `TS`, `SNES`, or `KSP`, only if you directly call `MatGetFactor()` so use the options
database approach when working with `TS`, `SNES`, or `KSP`. See `MATSOLVERMKL_CPARDISO` for the options
