MATLAB: How to define this intergral

integral

I am trying to find the integral between 0 and h but matlab keeps telling me that the int is not defined but every integral example i have checked seems to indicate that the integral is programmed into matlab but i can't find it. Is the formula below suitable to find the integral or am i missing something key. Any help would be appreciated.
h=2
Q=int(0,h)

You can use a quad function. Example a function f(x)=x^2+3
f= @(x) x.^2+3;
Q = quad(f,0,10)  % Integral between 0 and 10
