Forgive me if this has already been asked, but I'm trying to find out how to write a system on nonlinear equations as a function in MATLAB
for example:
a*(x(i))^2 + x(i-1) - x(i) = 0
How would I write this for any given size of x without writing the equations manually?
Would it be something like the following:
function y = myFunction(x)
y = a*(x(i))^2 + x(i-1) - x(i)
end

From my understanding you want to solve nonlinear equations. You can refer fsolve for more information.
