Hi! I have a set of points and I'd like to make a curvefitting using this custom equation:
y=(exp(a*x))*(1/((((20000/(1-0.5^2)).^b)).*0.7));
How can I do this with the built-in toolbox Curve fitting (even without it!)?
Thanking you for your attention, I'm looking forward for your answers.

If you have neglgible noise in your data, you can take the log of both sides and convert your model into a linear one
logy=a*x+b*log(constants)
Then you can just use a linear solver (backslash, linsolve, etc...)
