Evaluate fuction Sin(x)*Exp(-x^2) on interval [-PI/2, PI]. Use default Gauss base points and weights. 

 

private double IntFun(TVec x, TVec c, params object[] o) { double x = x[0]; return System.Math.Sin(x)*System.Math.Exp(-x*x); } private void Example() { TIntStopReason sr; double area = MtxIntDif.QuadGauss(IntFun,-0.5*System.Math.PI, System.Math.PI, out sr, 1.0e-4, 8); }
