</span><br><span class=help> <span class=help_field>Synopsis:</span></span><br><span class=help> [X,Y] = ellips(Center,Shape,radius,n)
</span><br><span class=help> [X,Y,Z] = ellips(Center,Shape,radius,n)
</span><br><span class=help>
</span><br><span class=help> <span class=help_field>Description:</span></span><br><span class=help> This function interpolates ellipse by lines in 2d space
</span><br><span class=help> or by patches in 3d space respectivelly. The ellipsoid
</span><br><span class=help> is described as
</span><br><span class=help> radius^2=(x-Center)'*Shape*(x-Center).
</span><br><span class=help>
</span><br><span class=help> The number of lines used for interpolation is given
</span><br><span class=help> by argument n in 2d case. In 3d case the argument
</span><br><span class=help> n has the same meaning in the Matlab function sphere(n).
</span><br><span class=help>
</span><br><span class=help> <span class=help_field>Input:</span></span><br><span class=help> Center [2x1] or [3x1] Center of the ellipse.
</span><br><span class=help> Shape [2x2] or [3x3] Shape of the ellipse.
</span><br><span class=help> n [1x1] Density of interpolation (default 20).
</span><br><span class=help>
</span><br><span class=help> <span class=help_field>Example:</span></span><br><span class=help>
</span><br><span class=help> 2d ellipse
</span><br><span class=help> [x,y] = ellips([1;1],[1 0.5;0.5 1],1);
</span><br><span class=help> figure; plot(x,y);
</span><br><span class=help>
</span><br><span class=help> 3d ellipsoid
</span><br><span class=help> [x,y,z] = ellips([1;1;1],[1 0 0;0 2 0; 0 0 3],1);
</span><br><span class=help> figure; mesh(x,y,z);
