I have y (concentration) and x (time) data for a reaction that can be modeled by the following function:
F(x) = k*L0*((m/(g*h))+((h-m)/(g*(g-h))*exp(-h*x))+((m-g)/(g*(g-h)))*exp(-g*x))+2*k*l*L0*(1/(g*h)+(exp(-g*x)/(g*(g-h)))-(exp(-h*x)/(h*(g-h))))
where g*h=k*(l+m) and g+h=k+l+m.
My only variables are x and y and all other parameters are constants, all I want to do is fit my data to this function to solve for k, l, and m.
Could anybody please help me with writing this code or suggest a resource that might help me?
