lvconj(3)

LIBRARY ROUTINE
lvconj -

LIBRARY CALL
#include "vinclude.h"
int
lvconj(f1)
struct xvimage *f1;

INPUT

    f1 -- xvimage strcuture

OUTPUT

    f1 -- holds the result of the multiply operation. The output data type is the same as the input data type.
    f1 is used for both the input xvimage structure and the output result xvimage structure. This is done to save space, but you must be careful not to overwrite important data.

MODIFICATIONS
Feb 27-91 JW/SL Added support for double complex images.

DESCRIPTION
vconj computes the complex conjugate of the input image.

The input file must be COMPLEX or DOUBLE COMPLEX. The output file is obtained by negating the imaginary part of the complex pair.

To perform auto and cross correlations, apply vfft, vconj, and vmul.

The output file is an COMPLEX image.

ARGUMENTS
-i input image
-o output image

RESTRICTIONS
NOTE: This routine supports only the COMPLEX type!
