comment Matlab integral with parameter
Matlab's quadgk does allow integration over infinite intervals (as long as the integrand decays rapidly enough). Its methods are rather more sophisticated, I think, than picking a finite cutoff.

comment Can a quadratic be solved with matrices?
Matlab, for example, finds the roots of a polynomial (numerically) by constructing the companion matrix and computing its eigenvalues.

comment Where have I used the assumption that $X\in L_2$?
It is correct. You didn't use that assumption, and it isn't needed.
