Passing waves for user defined fit function

Share icon

Is it possible? and How?
No, AFAIK this is not possible. See 
DisplayHelpTopic "User-Defined Fitting Function: Detailed Description"
for the details.

Is the standard solution a la

Function F(w, x) : FitFunc
	WAVE w
        Variable x

        Wave root:myWave // additional wave

	<body of function>
	<return statement>
End

not viable for you?

It is possible using a structure fit function. But they are difficult to use- structures can only exist inside a user-defined function, so FuncFit has to be called from within a driver function.

Otherwise, use the solution proposed by thomas_braun.
