## The FFTW library (Discrete Fourier Transform)

This week, I built from source code a discrete Fast Fourier Transform library known as “The Fastest Fourier Transform in the West”, or FFTW for short. This library can be used along with the GCC C or Fortran compilers on many operating systems and architectures to compute the Discrete Fourier Transform. I tested it with the short test “make check” and the much longer test “make bigcheck”, and all tests were passed. I have some data that I wish to apply the FFT to. I may report back later here on further developments in my actual use of the FFTW library. The documentation is very extensive, and building and installing went very smoothly.
