ABSTRACT

  This package is an Ada version of Ferguson's FORTRAN 
program to compute the general N point fast Fourier
transform.  It was presented by the authors in an 
article titled "Analysis of an ADA Based Version of
Glassman's General N Point Fast Fourier Transform,"
which appears in "Computers & Mathematics with 
Applications," v26, n2, pages 61-65, 1993.  In the 
article, the package is compared with the original 
FORTRAN version.  It is demonstrated that the 
execution time of the Ada program is comparable to 
that of the corresponding FORTRAN program.
