sdfftm1dui(3F)

NAME
     sfftm1dui, dfftm1dui - Multiple 1D,  FFT Real to Complex workspace
     initialization routines.

FORTRAN SPECIFICATION
     subroutine SFFTM1DUI( n, workspace )
     integer              n
     real                 workspace(*)

     subroutine DFFTM1DUI( n, workspace )
     integer              n
     double precision     workspace(*)


C SPECIFICATION
     float     *sfftm1dui( int n, float  *workspace)

     double    *dfftm1dui( int n, double *workspace)


DESCRIPTION
     SFFTM1DUI and DFFTM1DUI initialize the array WORKSPACE which is used in
     SFFTM1DU and DFFTM1DU. The prime factorization of N, together with a
     tabulation of the trigonometric functions, are computed and stored in
     WORKSPACE.

     NOTE: These routines are provided only for compatibility with previous
     releases of complib.

PARAMETERS
     N - INTEGER.
     On entry, N specifies the number of elements in the sequence to be
     transformed.  Unchanged on exit.

     WORKSPACE - Array.
     A work array which must be dimensioned at least N + 15.

     On exit, WORKSPACE will contain the prime factorization of N, together
     with a tabulation of the trigonometric functions.
