I would greatly appreciate some advice or an example from those functions. <BR /><BR />Rentzi the pitiful coder Tue, 01 Nov 2005 03:37:22 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Problem-with-zheev-Please-help-if-you-can/m-p/965550#M16198 eren 2005-11-01T03:37:22Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Problem-with-zheev-Please-help-if-you-can/m-p/965551#M16199 What is the matrix? <DIV></DIV> Mon, 07 Nov 2005 21:46:56 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Problem-with-zheev-Please-help-if-you-can/m-p/965551#M16199 michael_chuvelev 2005-11-07T21:46:56Z
