Hello everybody,
I'd like to use Matlab to calculate the following expression

C=∫x^4*exp(x)/(exp(x)-1)^2 dx with x[a,b].

I made the matlab code as following

f=inline('x.^4*exp(x)./(exp(x)-1).^2');
C=quad(f,a,b);

Could you please to tell me whether my code is right or not?
Are there any suggestions for solving the above expression?

Thanks in advance.

Hello,

I have a question regarding a integral computation:
I = A*cos(f*t)/((t/t0)^n+(t/t0)^m)

A, n, m, t0 are known constants
t= variable, and can take values between 1 and 3600

Could you please help me with the code? I would be greateful...

Thank you
