How can I approximate this integral with at least 6 exact decimals using a Gauss-Laguerre quadrature?
I split it into two integrals, one from [-inf,0] and another from [0, inf],the second one already being in a Gauss-Laguerre form, but the first one wasn't. I got stuck at the first one, I applied the x = -t substitution to try and flip the interval but that left me with exp(x) which isn't Gauss-Laguerre. How else could I have approached this?
