How to do integration using MATLAB
显示 更早的评论
how to get integral of (u^4*exp(u)/(exp(u)-1)^2) du with limit 0 to T (where T is temperature) in MATLAB. I want analytic solution in T where T value will be assigned later. I tried the following: >> u=sym('u')
u =
u
>> int((u^4*exp(u)/(exp(u)-1)^2)) Warning: Explicit integral could not be found.
ans =
int((u^4*exp(u))/(exp(u) - 1)^2, u)
>>

instead of using symbolic math you can use numerical integration .
function answer=myfunction(T)
%* Labatto quadrature –
q =quadl('(u.^4.*exp(u))./((exp(u)-1).^2)',0, T)
%you can use quad() and trapz() functions instead
end
