- Evalf now uses asymptotic series to numerically evaluate the following special functions for large : Si(x) and Ci(x) (Sine and Cosine integrals), Ai(x) and Bi(x) (Airy wave functions), erfc(x) (complementary error function), BesselJ(v,x) and BesselY(v,x) (Bessel functions and ).
- The efficiency of evaluating the elementary functions to high precision has also been improved - see section 7.
- Evalf of sum(f(r),r=RootOf(a(x),x)) sums over the complex roots of a polynomial .
- Dsolve has been extended to use a Runge-Kutta based numerical method for solving initial value ODE's.
- The library routines shake and evalr provide a model of interval arithmetic which is used to do simplifications of signum of exact real constants.
