INTEGRATION AND DIFFERENTIATION

- anlaysis with Xi -

For numerical integration and differentiation Xi computes a spline under tension through the data points. The use is straight forward:

(  1)>x=dincarr(100)/100;
(  2)>print(integrate(x,exp(x)+1,0,1));
<double> 2.71828
(  3)>print(derive(x,exp(x),{0,1}));
