"user-defined" curve fitting in a macro

[David Goldenberg]

Hi,
    I would like to include in a macro a curve fit to a non-standard
function, as implemented in the Analyze>Tools>Curve Fitting ... command.
To be clear, I want to include a specific function coded in the macro,
not prompt the user for a function.

I have figured out how to code curve fits to the pre-defined functions,
but I haven't found any documentation or examples that would allow me to
define a function within a macro.

Any help would be greatly appreciated.

Use the Fit.* macro functions described at

    http://rsbweb.nih.gov/ij/developer/macro/functions.html#Fit

Here are some examples:

Wayne,
    Thanks very much. That is just what I was looking for, and I
obviously hadn't looked hard enough for examples!
