 *  window. Memory required for dynamic programming (DP) matrices will
 *  be allocated and free'd on-the-fly. Hence, after return of this function, the recursively filled

 *
 *  @note In case you want to use the filled DP matrices for any subsequent post-processing step, or
 *  you require other conditions than specified by the default model details, use vrna_mfe_window(),
