Hi everyone,
I would like to fit a curve with 4 Gausses. The width of Gauss1 and Gauss 2 should be the same, while those of Gauss3 and Gauss4 are independent.
How can I set up the constrain that three width values w1 w3 and w4 are to be fitted and w1=w2.
Under constraints option I got syntax error message.
Thank you in advance |

Thank you very much for your reply. The error was that I wrote "w_2" instead of "w__2". Now the fitting works as I would like to :-) |

If you use Nonlinear Curve Fit tool, you can set the linear constraint as show blow. Make sure check the box to enable the constraints.
