MATLAB Online에서 열기 This solution relies on only one for-loop (although technically you could replace this for-loop, too). 'sumOut' is the solution to the equation. kMax = 10; out = zeros(1,kMax); fork = 1:kMax out(k) = sum(sin((pi + 0.1)./(1:k)) .* exp(-k/...

your problem well enough to be solvable. As of now you have told us that you have 4 coupled ODEs, where one coefficient will depend on the final solution. (This oviously breaks the causality of physics, and mathematically it doesn't make much sens...
