MATLAB求解定积分

Question

大家可以帮我看看这个定积分怎么用MATLAB求解吗，我用int解出来还是带int的式子

Answer 1

我发现直接算得，numeric.....
感觉可以这样迂回算。。。。

syms t A B T1;
fun = @(t)( A.*(exp(B.*t)+1)./(exp(B.*t)-1));
result1 = int(fun,t)
%pretty(result);
fun2 = @(t)((2*A*log(exp(B*t) - 1))/B - A*t);
result2 = fun2(T1)-fun2(0)

显示结果
result1 =

(2Alog(exp(Bt) - 1))/B - At

result2 =

(AInf)/B - AT1 + (2Alog(exp(B*T1) - 1))/B
