When performing Fourier transforms with Fourier[] I get a list of complex numbers, although I know that all the data are real. Can anyone advise me how to convert the result to real numbers. I guess it has to do something with the exponential in the Fourier algorithm. Is there a numerical Sin (or Cos) transform package? Any comment will be appreciated! Dimiter
