Integrate symbolic function & maintain constants in solutions

6 views (last 30 days)
Hi i am looking to integrate the below equation (F1) from 0->Inf
a(1), a(2), a(3) are just constants a1,a2,a3 and i'd like to see the solution to the integral with the constants in it.
FD = @(s) sqrt((a(1).^2+s).*(a(2).^2+s).*(a(3).^2+s)); F1 = @(s) 1./((a(1).^2+s).*FD(s));
Is this possible? the integrals can be evaluated if the values a(1) a(2) and a(3) are replaced with numbers.
Any help would be greatly appreciated

As I mentioned to you yesterday, you are unlikely to get a symbolic answer from 'int' as a function of a1, a2, and a3, because what you have there is an elliptic integral, and 'int' can't use any of the elementary functions available to it for expressing this function.
