Hi everybody, I have a question that if I have a function f=sin(t-D), I want to calculate the integral from t=0 to 1 with D=0:0.01:0.1 (10 values of D) So I want to get 10 result for this integral (D=0 to 0.1) How can I do that? I see some example on trap(), but I am not sure how can I apply it to my question. Many thanks. Jianyang

Since a closed-form symbolic solution does not exist, you will need to use a numerical method. You cannot get a simple expression; however, you can create an anonymous function which "acts" like an expression in terms of m and M.
f = @(s, m, M) sqrt(s)./((s-m.^2).^2+3*s).*exp(-s./M.^2);f_int = @(m, M) integral(@(s) f(s, m, M), 0.07, 1.5);Run it like this
>> f_int(1, 1)ans = 0.2519>> f_int(1, 2)ans = 0.4109You can then use it to solve for the equation using fsolve().
