In the MKL FFT csfft1dc call I load the real part of the frequency domain to time domainarray in the bottom of the float array and the complex in the top. Can I use the DFTI_REAL_REAL storage typewith theDFTI_REALdomain to achieve the same thing (with a slightly different position of the data in the float array)? I am confused about the difference between the Packing and the storage schemes. Can I use the storage scheme on p 11-42 #4 of the MKL reference manual and ignore the packing stuff to achieve a csfft1dc call?</FONT></DIV></DIV> Thu, 23 Jun 2005 02:32:08 GMT Intel_C_Intel 2005-06-23T02:32:08Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Structure-differences-between-FFT-and-DFT-calls/m-p/988053#M17883 <DIV> <DIV><FONT color="#000000">In migrating from MKL FFT to DFT I desire to use only real/float arrays.
