Hi Radwa,
It is my understanding that you're trying to evaluate a function in MATLAB that involves both arrays and summation, but you're encountering difficulties in combining the for loop and summation into a complete function. To address this, you can use vectorization and for loops to efficiently handle arrays and summations in your code.
Here is an sample implementation of the function in MATLAB:
function Gamma = evaluateFunction(nt, Var, Yr, K)
% Initialize result
Gamma = 0;
R = length(Yr) - 1;
% Loop over each K
for k = K
sum_zeta = 0;
for r = 1:R
gamma_r = Yr(r);
gamma_r1 = Yr(r+1);
% Calculate terms
term1 = (1 - exp(-nt * gamma_r1 * Var) / (1 + gamma_r1)^(nt-1))^k;
term2 = (1 - exp(-nt * gamma_r * Var) / (1 + gamma_r)^(nt-1))^k;
% Compute zeta_r
zeta_r = term1 - term2;
sum_zeta = sum_zeta + zeta_r;
end
% Compute Gamma_k
Bw = 1; % Define Bw as needed
Gamma_k = Bw * nt * (1 - (1 - 1/nt)^k) * sum_zeta;
Gamma = Gamma + Gamma_k;
end
end
% Example usage:
nt = 2;
Var = 1;
Yr = [0, 10^(-6.7/10), 10^(-4.7/10), 10^(-2.3/10), 10^(0.2/10), 10^(2.4/10), 10^(4.3/10), 10^(5.9/10), 10^(8.1/10), 10^(10.3/10), 10^(11.7/10), 10^(14.1/10), 10^(16.3/10), 10^(18.7/10), 10^(21/10), 10^(22.7/10)];
K = 5:15;
Gamma = evaluateFunction(nt, Var, Yr, K);
disp('Gamma:');
disp(Gamma);
Feel free to modify the code as per your needs.

Hope this helps!
