                                            <div>My parallel application
                                              written in C++ (which also
                                              uses PETSc library for
                                              linear solvers) requires
                                              calling control and
                                              optimization toolbox of
                                              MATLAB at every time step
                                              to get a small number of
                                              double values. Likewise
                                              the MATLAB function will
                                              need to know some values
                                              from the parallel C++
                                              application to return
                                              those doubles. I'm
                                              wondering if there is a
                                              recommended way of calling
                                              MATLAB from parallel
                                              C/C++/Fortran codes, and
                                              if PETSc has some
                                              interface that could be
