5903 Intro Scientific Prog:
Timing FFTs: Specification

1. Time one of the general gsl tranforms on a complete range of problem sizes. Graph and discuss the results.
2. Compare the timings of several matching gsl and FFTW 1D algorithms on a range of sizes of 1D problems.  I suggest a log plot of the time against problem size.  Discuss the results. 
3. Compare the timings of a single matching gsl and FFTW 2D transform.
