Fittype gauss1
WebDec 30, 2024 · mdl = fittype ('gauss1') mdl = General model Gauss1: mdl (a1,b1,c1,x) = a1*exp (- ( (x-b1)/c1)^2) In the end, you have 3 parameters. But now you want to find a mean and standard deviation. A problem is there is no presumption that the curve you have actually integrates to 1. So that tells me the parameter a1 is useless. WebCreate two fits using the custom equation, startpoints, and the two different excluded points. f1 = fit (x',y',gaussEqn, 'Start', startPoints, 'Exclude', exclude1); f2 = fit (x',y',gaussEqn, 'Start', startPoints, 'Exclude', exclude2); Plot both fits and highlight the excluded data.
