19 Apr 2010 fitellipse.m Fit ellipses to 2D points using linear or nonlinear least squares Author: Richard Brown

When I run the demo file (using 2007a), I get an error message:

??? Error using ==> minus
Matrix dimensions must agree.

Error in ==> fitellipse at 87
x = x - repmat(centroid, 1, length(x));

Error in ==> ellipsedemo at 58
[zb, ab, bb, alphab] = fitellipse(x, 'linear');

19 Apr 2010 error_ellipse Plot an error ellipse depicting confidence interval given a covariance matrix. Author: AJ Johnson

Very helpful optically - but can it calculate the area of the error ellipse? I couldn't easily get it to adapt to this. Any help would be great!
