18 Sep 2011	fitcircle.m Fits circles to 2D data using nonlinear least squares to minimise geometric error	Richard Brown	Hi Brian This code computes a least squares fit, which is not robust to large outliers - the results you got are not unexpected, nor are they wrong. Because the objective being minimised is a function of the square of the distance, big outliers will skew the fit. If your data is known to have significant outliers, least squares is not a good choice of objective to minimise. cheers, Richard	Comment only
30 Aug 2011	fitcircle.m Fits circles to 2D data using nonlinear least squares to minimise geometric error	Brian Wheeler	To test thus function I fed it data for a 360 point unit circle. As expected it returned a unit circle centered on zero. Distorting one point of the circle to a radius of 6 gave expected results: radius 1.01408739256055 center [ 3.76743045176789e-17 0.0281775669475842] Distorting the same point of the circle to a radius of 7 gave UNEXPECTED results: radius 3.258619140676808 center [1.25049755875451e-15 3.17478833187820] Thoughts anyone?
