I want to compute the following product of integrals numerically using the and the tool of Matlab:
where, are known scalar values gathered into a vector and f, g are two continuous and differentiable functions. Any ideas?

What ideas do you need? You have already said that integral() is the tool you are going to use. That does seem very appropriate.

Hi Dimitris,
Have a look at the following example code. I have assumed different functions for 'f' and 'g' and integrated their product from a lower bound of -2 to an upper bound of 2 using the 'int' function. There are 5 known scalar values here (n = 5), which I have gathered into a vector yi.
yi = 1:5;
syms x y
g(x,y) = x*y;
h = 1;
for i = 1:5
f(y) = yi(i)*y^3;
hi = int((f(y).*g(x,y)),y,-2,2);
h = hi.*h;
end
For more information on 'int', refer to the following link: int
Hope this helps!
Regards,
Divija
