Assigning computation values to variables without making it an array

Hi. When I use the following code it creates a array instead of just store a single value.

fa1=(1/T)*trapz(t1,f1);

How do I sotre just the value, since when I try rping the answer it prints an entire matrix

Provide the missing values

T=2*pi;
w0=1
t1=-pi:0.001:0;
f1=-(t1/pi);

t2=-0:0.001:pi;
f2=t2.*cos(3*t2);

fa1=(1/T)*trapz(t1,f1);
fa2=(1/T)*trapz(t2,f2);
sum1=fa1;
sum2=fa2;

for n=1:10
    sum1=sum1+((1/T)*trapz(t1,f1.*exp(-1j*n*w0.*t1))).*exp(1j*n*w0.*t1)...
    +((1/T)*trapz(t1,f1.*exp(1j*n*w0.*t1))).*exp(-1j*n*w0.*t1);

    sum2=sum2+((1/T)*trapz(t2,f2.*exp(-1j*n*w0.*t2))).*exp(1j*n*w0.*t2)...
    +((1/T)*trapz(t2,f2.*exp(1j*n*w0.*t2))).*exp(-1j*n*w0.*t2);

    disp([num2str(sum1+sum2)])
end

I suggest you check what terms are enclosed in your parentheses very closely.
