I’m trying to perform a resonant capture stellar reaction rate calculation and for those of you not familiar with one it basically involves a sum of many exponentials.
In my case that number is ~60. Each exp has a resonance strength parameter as well so that means ~120 parameters in a TF1.
I’ve attached my code, root cannot seem to perform the calculation saying it’s “too many operators” and I was wondering if anyone had a better idea how to code this using root or if it’s even possible. Thanks!
