Gaussian integral with complex coefficients
WebTools. In numerical analysis, Gauss–Legendre quadrature is a form of Gaussian quadrature for approximating the definite integral of a function. For integrating over the interval [−1, 1], the rule takes the form: where. n is the number of sample points used, wi are quadrature weights, and. xi are the roots of the n th Legendre polynomial. WebIn problem 1, we derived the Gaussian integral Z YN n=1 d˚ n exp ˆ 1 2 ˚TM˚+ jT˚ ˙ = (2ˇ)N=2 (detM)1=2 exp 1 2 jTM 1j (13) for a positive de nite, real and symmetric N Nmatrix M. In this problem, we want to consider integrals over complex ariablesv ˚ = (˚ 1;:::;˚ N). Here, you should not think of contour integrals in the complex plane!
