In c language, the type of the handle is sparse_matrix_t. How to wrap this kind of type in Julia ccall? I have used sparse_matrix_type_t as a pointer of `<EM>Cvoid</EM> `type in julia. But I am getting an error of "SPARSE_STATUS_INVALID_VALUE". What are the field names of the matrix_descr structure? It looks that mkl 2 stage algorithms are&nbsp;difficult to implement&nbsp; other than c language.</SPAN></P> Wed, 14 Oct 2020 20:11:11 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/sparse-matrix-t-handle/m-p/1217733#M30158 j_tanu 2020-10-14T20:11:11Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/sparse-matrix-t-handle/m-p/1218417#M30162 <P>have you tried to check this forum? if I am not mistaken, we had in the past a few topics that discussed how to make the mkl call from Julia.</P> <P>&nbsp;</P> Fri, 16 Oct 2020 15:38:07 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/sparse-matrix-t-handle/m-p/1218417#M30162 Gennady_F_Intel 2020-10-16T15:38:07Z
