Function: dctresample

DCTRESAMPLE   Resample signal using Fourier interpolation
  Usage:  h=dctresample(f,L);
          h=dctresample(f,L,dim);

  DCTRESAMPLE(f,L) returns a discrete cosine interpolation of the signal f*
  to length L. If the function is applied to a matrix, it will apply
  to each column.

  DCTRESAMPLE(f,L,dim) does the same along dimension dim.

  If the input signal is not a periodic signal (or close to), this method
  will give much better results than FFTRESAMPLE at the endpoints, as
  this method assumes than the signal is even a the endpoints.

  The algorithm uses a DCT type iii.
