%     This package consists of programs which perform Fast Fourier
%     Transforms for both complex and real periodic sequences and
%     certain other symmetric sequences that are listed below.
%
%     1.   RFFTI     Initialize RFFTF and RFFTB
%     2.   RFFTF     Forward transform of a real periodic sequence
%     3.   RFFTB     Backward transform of a real coefficient array
%
%     4.   EZFFTI    Initialize EZFFTF and EZFFTB
%     5.   EZFFTF    A simplified real periodic forward transform
%     6.   EZFFTB    A simplified real periodic backward transform
%
%     7.   SINTI     Initialize SINT
%     8.   SINT      Sine transform of a real odd sequence
%
%     9.   COSTI     Initialize COST
%     10.  COST      Cosine transform of a real even sequence
%
%     11.  SINQI     Initialize SINQF and SINQB
%     12.  SINQF     Forward sine transform with odd wave numbers
%     13.  SINQB     Unnormalized inverse of SINQF
%
%     14.  COSQI     Initialize COSQF and COSQB
%     15.  COSQF     Forward cosine transform with odd wave numbers
%     16.  COSQB     Unnormalized inverse of COSQF
%
%     17.  CFFTI     Initialize CFFTF and CFFTB
%     18.  CFFTF     Forward transform of a complex periodic sequence
%     19.  CFFTB     Unnormalized inverse of CFFTF
