These arrays can be used for the solution phase. So far, the factors are not available to export.</P> Fri, 18 Oct 2024 00:28:41 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/I-read-the-document-about-mkl-pardiso-what-does-this-means-To/m-p/1637925#M36548 Fengrui 2024-10-18T00:28:41Z Re: I read the document about mkl pardiso，what does this means?To compute schur,iparm[35]= -2 https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/I-read-the-document-about-mkl-pardiso-what-does-this-means-To/m-p/1637935#M36549 <P>Ok,thanks</P> Fri, 18 Oct 2024 01:17:14 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/I-read-the-document-about-mkl-pardiso-what-does-this-means-To/m-p/1637935#M36549 yimodao 2024-10-18T01:17:14Z
