computes power spectral density of one or two files
<in1> Input 1 file name <out1> File to receive PSD of input 1 <nfft> Desired transform size. Any factor supported [DEF=1k] <win> Name of time window to be computed and applied to the data [DEF=HANN] <over> The fraction of <nfft> to overlap blocks [DEF=0] <navg> Num of transforms to average in computing each output FFT frame [DEF=-1] <in2> Input 2 file name [OPTIONAL] <out2> File to receive PSD of <in2> [OPTIONAL] <cross> File to receive PSD of <in1> * conjugate of <in2> [OPTIONAL] This command performs Fast Fourier Transforms on a stream of data. It calls the FFT primitive with default navg=-1 and default switches /1D/PSD. To match X-Midas behavior add the /PARTIAL=NONE switch. See Also: FFT
