- Methods for calculating precise logarithm of a sum and subtraction
- License: Shareware
- Price: .price.

Disclosed are methods to compute the precise value of the logarithm of a sum and the logarithm of a subtraction. A number of practical problems can result in having too big or small values in intermediate values of a calculation. Then one tries to take logarithm of these values and operate on logarithms instead.

- Random numbers from a user defined piecewise polynomial distribution
- License: Shareware
- Price: .price.

All the information required to compute the random sequence are extracted from the pp-form structure, in particular the lowest and the highest generated numbers corresponds to the first and last break of the pp form respectively. RANDPDFS uses FNINT to compute the cumulative distribution function, therefore spline toolbox has to be accessible to allow RANDPDFS to work properly.

ode86 Integrates a system of ordinary differential equations of the form dy/dx=f(x,y), y(x0)=y0, using a 12-stages, 8th and 6th order Runge-Kutta pair of formulas. The method advances using the higher order formula (using local extrapolation). The results are expected to be better than ODE45 for tolerances stringent than 1e-6.
