FFTPACK++ - C++ version of FFTPACK

Most of this code was lifted directly from GNU OCTAVE v1.1.0, hence the copyright notice at the top.

The forward FFT takes you to freq domain (ala direction == -1), and backward the other way.

Passing LaVectorComplex/Double or LaGenMatComplex/Double with one dimension set to 1 will implicitly perform 1D FFT on the data.

The members of the FFT_Pack class are declared static, since they really need no private member storage. There are two types of transform routines: ones that return a new complex matrix and the ones that change the matrix in place.

The original FFTPACK does not appear to be available any more, but I found the link below to a different (possibly improved) version.
