recently my research project is involved in a Fourier Transformation
integration. it is just integrate over f(x)cos(x), where f(x) is a 
relatively smooth function. i tried a Fourier transformation routine
in the IMSL liabrary. however it is extremely slow. do netters have
similar experience? i need a good routine badly. all suggestions are
welcome.
