Since I'm on MKL 7.2 currently I cannot provide my own 'malloc' function which could use a pre-allocated buffer.</P> Sat, 03 Feb 2007 05:40:33 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Reuse-DFT-descriptors/m-p/885042#M9978 lhartzman 2007-02-03T05:40:33Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Reuse-DFT-descriptors/m-p/885043#M9979 <P>I've discovered that you can reuse the descriptor.
