However, the spectrum can be shifted by processing of the data in O(n) time. <A title="Rearranging matrix elements" href="http://software.intel.com/en-us/forums/showthread.php?t=65955">This topic</A> might be helpful.<BR /><BR />Thanks<BR />Dima<BR /> Thu, 15 Oct 2009 09:06:23 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Is-there-a-corresponding-fftshift-function-in-MKL/m-p/847177#M6332 Dmitry_B_Intel 2009-10-15T09:06:23Z
