Syntax

[V]=ellipseCoord3(e,t);

Description

Calculates ellipse coordinates for the angles in t based on the input structure e which contains the following fields: radii, a 2x1 array axes, a 3x3 rotation matrix centre the ellipse centre coordinates

Examples

%Define example input data

%Angles
t=linspace(0,2*pi);

%Centre coordinates
Vc=[2 2 2];

%Radii
r=[1 2];

%Rotation matrix
Q=euler2DCM([0 -0.25*pi 0.25*pi]);

%Compose input structure
e.centre=Vc;
e.radii=r;
e.axes=Q;

%Compute ellipse coordinates
V=ellipseCoord3(e,t);
