NAME    [Toc]    [Back]

     sfft1dui, dfft1dui	- 1D FFT Real to Complex workspace initialization
     routines.

FORTRAN	SPECIFICATION
     subroutine	SFFT1DUI( n, workspace )
     integer		  n
     real		  workspace(*)

     subroutine	DFFT1DUI( n, workspace )
     integer		  n
     double precision	  workspace(*)

C SPECIFICATION    [Toc]    [Back]

     double  *dfft1dui(	int n, double *workspace);

     float   *sfft1dui(	int n, float *workspace);

DESCRIPTION    [Toc]    [Back]

     SFFT1DUI and DFFT1DUI initialize the array	WORKSPACE which	is used	in
     SFFT1DU and DFFT1DU. 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    [Toc]    [Back]

     N - INTEGER.
     On	entry, N specifies the length of the sequence to be transformed.
     Unchanged on exit.

     WORKSPACE - Array.    [Toc]    [Back]
     A work array which	must be	dimensioned at least N + 15.  It requires N
     elements for the sines and	cosines, plus 15 elements for the
     factorization of N.
