[Gretl-users] Re: Accesing the Hurst Exponent C/C++ API

Thank you very much, I was able to get to work. Below are two ways of doing it Method 1. double my_hurst_exponent = (double)hurstplot(list, dset, opt,prn); gretl_matrix *hurst_mat; void *tmp = NULL; GretlType *hurst_;// = &GRETL_TYPE_MATRIX; //hurst_mat = reinterpret_cast<gretl_matrix *>(get_last_result_data (hurst_, &err)); tmp = get_last_result_data (hurst_, &err); if(!err){ if(*hurst_ == GretlType::GRETL_TYPE_MATRIX){ hurst_mat = reinterpret_cast<gretl_matrix *>(tmp); std::cout<<hurst_mat->val[0]<<std::endl; } } Method 2. double my_hurst_exponent = (double)hurstplot(list, dset, opt,prn); gretl_matrix *hurst_mat; void *tmp = NULL; GretlType *hurst_;// = &GRETL_TYPE_MATRIX; hurst_mat = reinterpret_cast<gretl_matrix *>(get_last_result_data (hurst_, &err)); riley
