F95 INTERFACE
SUBROUTINE WIENER(N_POINTS, ACOR, XCOR, FLTR, EROP, ISW, IERR)
INTEGER :: N_POINTS, ISW, IERR
REAL, DIMENSION(:) :: ACOR, XCOR, FLTR, EROP
SUBROUTINE WIENER_64(N_POINTS, ACOR, XCOR, FLTR, EROP, ISW, IERR)
INTEGER(8) :: N_POINTS, ISW, IERR
REAL, DIMENSION(:) :: ACOR, XCOR, FLTR, EROP
C INTERFACE
#include <sunperf.h>
void swiener(int n_points, float *acor, float *xcor, float *fltr, float
*erop, int *isw, int *ierr);
void swiener_64(long n_points, float *acor, float *xcor, float *fltr,
float *erop, long *isw, long *ierr);
PURPOSE
swiener performs Wiener deconvolution of two signals.
ARGUMENTS
N_POINTS (input)
On entry, the number of points in the input correlations.
Unchanged on exit.
ACOR (input)
On entry, autocorrelation coefficients. Unchanged on exit.
XCOR (input)
On entry, cross-correlation coefficients. Unchanged on exit.
FLTR (output)
On exit, filter coefficients.
EROP (output)
On exit, the prediction error.
ISW (input)
On entry, if ISW .EQ. 0 then perform spiking deconvolution,
otherwise perform general deconvolution. Unchanged on exit.
IERR (output)
On exit, the deconvolution was successful iff IERR .EQ. 0,
otherwise there was an error.
