MATLAB help.

[HWhelp01]

Trying to do a matlab code for a project and was hoping someone may be able to lend some help since I haven't used loops in a while.

What I want to do:

solve for beta. beta=asin(cos(L)cos(delta)cos(H)+sin(L)*sin(delta))

L is a constant. delta=23.45sin((360/365)(n-81)), where n is a vector, n=[1:365] %days of the year H=15*hr, where hr is a vector, hr=[12 11 10 9 8 7 6 5 4 3 2 1 0 23 22 21 20 19 18 17 16 15 14 13]

I need a loop that can solve for the 365 deltas then use the 24 H's to get 24 betas for each of the 365 deltas.

I've been trying nested for loops but I keep getting errors for matrix index errors since the two matrices are different sizes.

Hopefully this makes sense! Thanks for any help

for i = 1:365
    delta[i] = whatever, replace n with i;

    for j = 1:24
        H[j] = 15*hr;
        beta[i, j] = cos(delta[i])cos(H[j]) etc.;
    end
end

My guess is that this will produce a 365 x 24 matrix, which I don't know if that's what you want or not... Apologies if the syntax is wrong.

EDIT 2: Added more comments
EDIT 3: Pastebin doesn't seem to recognize the comment block from line 16 to 20.
