Suppressing Output MATLAB

My code output gives me if, exact_answer, and then a vector output with N entries. I am unsure how to suppress that entry. For example, it looks like the following:

exact_answer =

    0.2642


If =

    0.1882


ans =

         0    0.1637    0.2681    0.3293    0.3595    0.3679

I don't want the answer output. -

function g = LaplaceTransform(s,N)
        % define function parameters
        a=0; 
        b=1;
        h=(b-a)/N;
        x = 0:h:1;
        % define function
        g = ff(x).*exp(-s*x);

% compute the exact answer of the integral
exact_answer=antiderivative(b,s)-antiderivative(a,s)
% compute the composite trapezoid sum
If=0;
for i=1:(N-1)
    If=If+g(i).*h;
end;
If=If+g(1).*h/2+g(N).*h/2;
If

ans shows up because you call

LaplaceTransform(bla, blabla)

instead of

LaplaceTransform(bla, blabla);

(you lack a semicolon when you call the function).

exact_answer shows up because your line

exact_answer=antiderivative(b,s)-antiderivative(a,s)

lacks a semicolon as well, you should have

exact_answer=antiderivative(b,s)-antiderivative(a,s);
