Use assume() on find_fit

asked 2012-06-21 16:24:13 +0200 gravatar image

Hi everyone,

does anyone know how I can use assumptions with find_fit? A minimal example would be


and the output is

[a == -105.66654155674746, b == -104.30685450333799]

Any help or hint on where to find a solution is appriciated. Thanks in advance.

Considering that `find_fit` uses Scipy and assumptions are in Maxima, I think it's quite unlikely that this would do much. I guess we could try to run them through assumptions, though this might slow it down appreciably.

You could fake it like this:


So the best fit values of a,b are negative, but their absolute values are a "good fit" in your model.
