Gauss hermite quadrature formula
WebFeb 23, 2010 · HERMITE_RULE is a C++ program which generates a specific Gauss-Hermite quadrature rule, based on user input. The rule is written to three files for easy use as input to other programs. The Gauss-Hermite quadrature rule is used as follows: c * Integral ( -oo < x < +oo ) f (x) exp ( - b * ( x - a )^2 ) dx. is to be approximated by.
