Hi. I have a series of functions that go Weight_Approx_1 -> Geometric_Approx -> Weight_Approx_2 . I would like for the Weight_Approx_2 to feed back in to Weight_Approx_1 so it can act as the new input. I can do this so well that I get an infinite loop without trying. How do I get a loop like this to return a final value from the Weight_Approx_2 program after a number of iterations I choose?

In other words, how do I rewrite a series of functions like below such that I control how many times f_c gets run? Once int == 2, it'll just be an infinite loop

function a = fa

for int = (1:10)

if int = 1

a = 1;

else

a = fc;

end

end

end

function b = fb

b = fa*2

end

function c = fc

c = fb + 1;

end

I'm not sure the code you've written describes what you intend. It's going to create an unterminated recursion that will cause an error very quickly.

Can you describe in words a little more clearly what you mean? Why are you using recursion at all? Why not something like:

x = 1; % whatever your initial estimate of the "thing" is

for k = 1:max_iterations

a = weight_approx_1(x);

b = geometric_approx(a);

x = weight_approx_2(b);

end
