Syntax

[V]=ellipseCoord(A,t);

Description

Calculates ellipse coordinates for the angles in t based on the vector A which defines the centre coordinates, the radii and the angle respectively.

Examples

%Define example input data

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

%Centre coordinates
xc=2;
yc=2;

%Radii
r1=1;
r2=2;

%Orientation angle
a=0.25*pi;

%Compose A
A=[xc yc r1 r2 a];

%Compute ellipse coordinates
V=ellipseCoord(A,t);
