# PetscOptionsScalarArray
Gets an array of `PetscScalar` values for a particular option in the database. The values must be separated with commas with no intervening spaces. Logically Collective on the communicator passed in `PetscOptionsBegin()`


## Synopsis
```
#include "petscsys.h"
PetscErrorCode PetscOptionsScalarArray(const char opt[],const char text[],const char man[],PetscScalar value[],PetscInt *n,PetscBool  *set)
```

## Input Parameters

- ***opt -*** the option one is seeking
- ***text -*** short string describing option
- ***man -*** manual page for option
- ***n -*** maximum number of values allowed in the value array



## Output Parameters

- ***value -*** location to copy values
- ***n -*** actual number of values found
- ***set -*** `PETSC_TRUE` if found, else `PETSC_FALSE`




Must be between a `PetscOptionsBegin()` and a `PetscOptionsEnd()`
