Does anyone know why this error occurs when "fit" is called? My data contain no NaN or Inf.

Warning: NaN, Inf, or complex value detected in startpoint; choosing random starting point instead. > In curvefit.attention.Warning/throw (line 30) In fit>iFit (line 299) In fit (line 108) In MyCode (line 47) >>

Danke, Stephan. Ja, der Anfangspunkt wurde von MATLAB bestimmt. Um dieses Problem zu vermeiden habe ich in Zukunft vor, ihn selber zu bestimmen.

Gruesse

Are you really sure?

Set a breakpoint in line 47 of your function MyCode, and check the values you enter into fit ...
