Integration of a function with variable parameter
显示 更早的评论
I have a function say f(tau)=lambda(tau) /exp(t-tau) where lambda is not an explicit function of tau. lambda has numeric values that are created inside a for loop and within each loop i need the integral value of f(tau) that considers all the value of lambda current and past. how do I do it? Please anyone can help?
I have attached an example code so it's easies to follow.

Please don't ask your question every two hours until you get an answer. You have now gotten answers on BOTH of these identical questions.

Do you mean something like this?
H = @(tau, lam, tt) lam./exp(tt-tau);
T=50;
step=1000;
h=T/step;
t=0:h:T;
lambda = rand(1,step+1);
tau = 1;
y = H(tau,lambda,t);
I = cumtrapz(y)*h;

subplot(2,1,2)
plot(t,I),grid
