Thanks!

16 May 2011 Stellaria (Tech Demo) - The best MATLAB shooting game ever If you think you have played the best MATLAB game before. Think again after you try this one. Author: Mingjing Zhang

Well done! Clean, robust, stylish, and smooth. Ignore the author's own humble words regarding coding quality!

Thanks Mingjing for the excellent suggestion!

30 Sep 2009 gaussian curve fit gaussian curve fit Author: Yohanan Sivan

I disagree with Matheca. The function is intended to fit a general gaussian, not necessarily a probability distribution function. The equation is correct.

However, the user should be aware that removing data points in a deterministic manner (i.e. by thresholding) definitely skews the resulting fit.

Rather than fitting to the whole series with negatives removed, try finding the largest contiguous positive subset of the original data series and fitting to that. This method won't work when the noise amplitude is greater than the distribution amplitude, but in most cases it will give you a better fit.

Even better yet: if accuracy is more important than computation speed, use fmincon with a least-squares difference cost function:

p = fmincon(@(p) sum((y-(p(1)*exp(-(x-p(2)).^2/2/p(3)^2))).^2),...
[max(y) mean(x) 1],[],[],[],[],[0 -inf 0],[2*max(y) inf inf])
A=p(1);
mu=p(2);
sigma=p(3);

Dude it is really cool, but I think we can make it even better... Sent you an email about a possible way to improve its performance. Please check it out.
