Using Nested Loops to calculate an equation

Ti = [-20 0 15 33 52];

P = [30 60 75 100];

A = [2 1.5 1] *10^(-5);

Tf_all = zeros(1,length(Ti)*length(P)*length(A));

ii = 1; % counter

sigma = 5.6696*10^(-8);

for t = 1:length(ti)

for p = 1:length (P)

for a = 1:length(A)

Tf_all(ii) = nthroot((P/(sigma*A))+Ti,4)

ii = ii+1;

end

end

end

disp(Tf_all)

This is the equation of a lightbulb filament. I was just wondering, how do you know the order of the nested loops, or does it not even matter?

You forgot indices:

Tf_all(ii) = nthroot((P(p)/(sigma*A(a)))+Ti(t),4);

I think the order doesn't matter in this case
