Description

The documentation for the XorS (cvXorS) function on this page:

http://opencv.willowgarage.com/documentation/python/operations_on_arrays.html#xors

Contains the extraneous comment

The code should print:

(1.0,0.0) (0.0,-1.0) (-1.0,0.0) (0.0,1.0)

Either the code which produces this is missing, or this is in the wrong section of the documentation.

The missing code is:

The following sample demonstrates how to conjugate complex vector by switching the most-significant bit of imaging part:

float a[] = { 1, 0, 0, 1, -1, 0, 0, -1 }; /* 1, j, -1, -j /
 [[CvMat]] A = cvMat( 4, 1, CV_32FC2, &a );
 int i, neg_mask = 0x80000000;
 cvXorS( &A, cvScalar( 0, *(float)&neg_mask, 0, 0 ), &A, 0 );
 for( i = 0; i < 4; i++ )
    printf("(%.1f, %.1f) ", a[i*2], a[i*2+1] );

This was taken from the old documentation at IU (Indana University)
