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!
