Integration

[Patrick Dupre]

Hello,


Can I collect your suggestions:

I need to make the following integration:

int_a^b g(x) f(x) dx

where a can be 0 of -infinity, and b +infinity
g(x) is a Gaussian function
f(x) = sum (1/((x-x0)^2 + g)) / (1 + S* sum (1 / ((x-x0)^2 + g)))

Typically, f(x) is a fraction whose numerator is a sum of Lorentzians
and the denominator is 1 + the same sum of Lorentzians weighted by a factor.

Thank for your suggestions
