MATLAB: While loop until x amount correct digits

while

Can someomene give me an example or an general way to write a while loop where the condition is that you need to have 3 correct decimals. ?

In my code I have a for loop but I need to make it more adapt.

Have you considered using built-in function 'round'?

Then you can just do:

if round(x,3) == round(y,3)
    ...
end

u2(n+1) = uc(n);
    u3(n+1) = uv(n);
    u4(n+1) = ut(n);
    u5(n+1) = ui(n);
    h = u5(n+1);

But it seems your algorithm needs improvement

[maxta1, maxidx] = max(ta1);
[minta1, minidx] = min(ta1);

That minidx and maxidx would be layer numbers.

However, I do not understand about Lakhs in this? Lahks I understand is 10^5 but you only have 50 layers. Are you looking for maxidx/10^5 ?
