Least square fitting
You can also use the ezyfit toolbox. http://www.mathworks.com/matlabcentral/fileexchange/10176-ezyfit-2-30 Recognising the error function, you can fit your data with showfit('P(A) = 100*erf((A-theta)/sigma); sigma=1e-4; theta=1e-4'); yielding: sigma = 0.00040156 theta = 4.8345e-005 Frederic. ... 23 Apr 2010 17:34
