Parameters

n

[input] the number of scatters

x

[modify] the X-coordinates of the points

y

[modify] the Y-coordinates of the points

z

[modify] the Z-coordinates of the points

nMethod

[input] the method to calculate the Z value on the duplicates.

0 replace with mean

1 median

2 min

3 max

4 sum

dPrecision

[input] tolerance to determine whether two points are duplicated.

Return

return the number of unique points in (x,y,z).

Examples

EX1

#include <wks2mat.h>        
void    xyz_remove_duplicates_ex1()
{
    vector vX = {1, 2, 3, 4, 6, 6, 6, 3, 6, 5};
    vector vY = {1, 2, 3, 4, 6, 5, 6.00001, 3, 6, 4};
    vector vZ = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
    double dPrec = 1e-7;
    int nPoints = xyz_remove_duplicates(vX.GetSize(), vX, vY, vZ, 0, dPrec);
    out_int("Number of unique points : ", nPoints);
