# PetscMatlabEnginePut
Puts a Petsc object, such as a `Mat` or `Vec` into the MATLAB space. For parallel objects, each processor's part is put in a separate  MATLAB process. 
## Synopsis
```
#include "petscmatlab.h"  
PetscErrorCode PetscMatlabEnginePut(PetscMatlabEngine mengine, PetscObject obj)
```
Collective


## Input Parameters

- ***mengine -*** the MATLAB engine
- ***object -*** the PETSc object, for example Vec





## Note
`Mat`s transferred between PETSc and MATLAB and vis versa are transposed in the other space
(this is because MATLAB uses compressed column format and PETSc uses compressed row format)
