4.9 sdds2dfft

• description: sdds2dfft performs two-dimensional fast Fourier transforms of data stored in SDDS tables. One column is taken as the independent variable while the remaining numerical columns are transformed. Options allow complex input, power spectral density output, normalization and more.
• examples:
  sdds2dfft image.sdds fft.sdds -columns=t,Image*
