When using the 64 bits fortran wrapper FFTW to perform complex one domensional FFT transform you must use the following string to create a plane:<BR /><BR />call fftwnd_f77_create_plan(planf,1,ngpt,FFTW_FORWARD,FFTW_ESTIMATE+FFTW_IN_PLACE)<BR /><BR />where:<BR /><BR />planf=name of the plane for FFT<BR />ngpt=number of point in the vector to FFT trasform<BR />1=number of dimension <BR /><BR />otherwise you will not be able to FFT stransform you dataset.<BR /><BR />In the 32 bits version of the FFTW library you may also avoid to insert 1 after the plan variable in case of one dimensional FFT transform.<BR /><BR />have a nice day!<BR /><BR />Lorenzo<BR /><BR /><BR /> Wed, 31 Aug 2011 13:48:00 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/1D-MKL-FFTW-64bits-intel-compiler-MacOs/m-p/763216#M57 lcolumbo 2011-08-31T13:48:00Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/1D-MKL-FFTW-64bits-intel-compiler-MacOs/m-p/763217#M58 <P>Lorenzo, </P><P>Thanks for sharing such information. </P> Fri, 02 Sep 2011 06:28:05 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/1D-MKL-FFTW-64bits-intel-compiler-MacOs/m-p/763217#M58 Chao_Y_Intel 2011-09-02T06:28:05Z
