Check if Points Inside an Ellipsoid

Checks if points are inside an ellipsoid

This tool checks if points are inside an ellipsoid. Example file is provided.

function I=CheckPointEllipsoid(Ellipsoid,vp)

Input:

Ellipsoid is (1*9) array. each cell represent:

(1): radius of ellipsoid at direction 1

(2): radius of ellipsoid at direction 2

(3): radius of ellipsoid at direction 3

(4): x-cooridante of centroid

(5): y-coordinate of centroid

(6): z-coordinate of centroid

(7): Inclination angle 1

(8): Inclination angle 2

(9): Inclination angle 3

vp is (3*N) coordinate matrix of N points.

output:

I is (1*N) logical vector containing 0 and 1. The value is 1 is if the point is inside the ellipsoid and 0 if it is outside.
