NAME    [Toc]    [Back]

     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    [Toc]    [Back]

     float     *sfftm1dui( int n, float	 *workspace)

     double    *dfftm1dui( int n, double *workspace)

DESCRIPTION    [Toc]    [Back]

     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    [Toc]    [Back]

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

     WORKSPACE - Array.    [Toc]    [Back]
     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.
