# PetscMatlabEngineGet

Gets a variable from MATLAB into a PETSc object.

## Synopsis

    #include "petscmatlab.h"
    PetscErrorCode PetscMatlabEngineGet(PetscMatlabEngine mengine, PetscObject obj)

Collective

## Input Parameters

- mengine - the MATLAB engine

- obj - the PETSc object, for example a `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)
