MATLAB: How to calculate integral of a function

integration

Hello Friends, I am new for matlab, I want to calculate a integral but I don't know, how should I do it exactly. My matlab code is here:
_________________________________________________________________________________________________
clear all;
format long;
T = 0.6;
m = 3.00;
kmin = 1.0;
kmax = 10.0;
fun = @(k) k.^2/exp(sqrt(k.^2 + m.^2)/T) + 1;
q = int (fun,kmin,kmax);
_________________________________________________________________________________________________
When I execute the program I got error message:
*??? Undefined function or
method 'int' for input
arguments of type
'function_handle'.
Error in ==> nudenNccbar at 14
q = int (fun,kmin,kmax);*_ *
Please help me to short out the problem. Thank you.

The function is quad, quadl, or quadgk:
fun = @(k) k.^2./exp(sqrt(k.^2 + m.^2)/T) + 1;
quad(fun,kmin,kmax)
ans = 9.0267
quadl(fun,kmin,kmax)
ans = 9.0268
quadgk(fun,kmin,kmax)
ans = 9.0268
Please note that a "." was missing in your equation (before the "/").
