I get the different results from zheev for the input matrix 70x70 when I use ('version of MKL libraries 10.2.2.025 and fortran compiler version /intel/Compiler/11.1/056/mkl/lib/32' that give correct results) and ('MKL libraries 10.2.3.029 and fortran compiler version intel/Compiler/11.1/064/mkl/lib/em64t/' that give incorrect results).<BR />Can somebody tell me where is the problem?<BR />Thanks<BR />Vlada Tue, 13 Jul 2010 12:04:05 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/different-results-for-zheev/m-p/780400#M1441 vladaz 2010-07-13T12:04:05Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/different-results-for-zheev/m-p/780401#M1442 It would be very helpful if you provided source code to demonstrate the behavior that you described.
