# PetscObjectTypeCompare
Determines whether a PETSc object is of a particular type. 
## Synopsis
```
#include "petscsys.h"    
PetscErrorCode PetscObjectTypeCompare(PetscObject obj, const char type_name[], PetscBool *same)
```
Not Collective


## Input Parameters

- ***obj -*** any PETSc object, for example a `Vec`, `Mat or `KSP`.
This must be cast with a (`PetscObject`), for example,
`PetscObjectTypeCompare`((`PetscObject`)mat);
- ***type_name -*** string containing a type name



## Output Parameter

- ***same -*** `PETSC_TRUE` if they are the same, else `PETSC_FALSE`
