# PetscObjectBaseTypeCompareAny
Determines whether a PETSc object has the base type of any of a list of types. 
## Synopsis
```
#include "petscsys.h"    
PetscErrorCode PetscObjectBaseTypeCompareAny(PetscObject obj, PetscBool *match, const char type_name[], ...)
```
Not Collective


## Input Parameters

- ***obj -*** any PETSc object, for example a `Vec`, `Mat` or `KSP`.
This must be cast with a (`PetscObject`), for example, `PetscObjectBaseTypeCompareAny`((`PetscObject`)mat,...);
- ***type_name -*** array of strings containing type names, pass the empty string "" to terminate the list



## Output Parameter

- ***match -*** `PETSC_TRUE` if the type of obj matches any in the list, else `PETSC_FALSE`
