How to take an integral symbolically and then convert it to type double?

How do I take the following integral symbolically? And convert it to double? I have a 1000 x 1 numeric vector of type double for A(t).
The following takes a minute or two to run and I'm not sure how to plot it to check.
syms t omega real
int(A*sin(omega*t),0,2*pi/omega)

format long g
syms t omega real
A = rand(5,1)
Asym = sym(A);
symbolic_result = int(Asym*sin(omega*t),0,2*pi/omega)
omega = abs(randn())
numeric_result = integral(@(t) A .* sin(omega.*t), 0, 2*pi./omega, 'Arrayvalued', true)
Zero to within round-off error.

syms t omega real
A = rand(1000,1);
% specify the integration variable t as the argument
I = double(vpa(int(A.*sin(omega*t),t,0,2*pi/omega),2))

Assuming some random data, you can specify the integration variable t as the argument and do symbolic integration
