https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/DFT-algorithm/m-p/893006#M10563 Hi,<BR /><BR />For the DFT, there is an option to choose between speed and accuracy. I was wondering if someone could tell me about the algorithm used for each of them.<BR /><BR />Thanks<BR /><BR />Kavi<BR /> Tue, 02 Sep 2008 21:42:31 GMT k_doshi 2008-09-02T21:42:31Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/DFT-algorithm/m-p/893006#M10563 Hi,<BR /><BR />For the DFT, there is an option to choose between speed and accuracy.
