Cubic Spline System   (details) 49/50 ENG   188 KB / 4 KB
Cubic spline system program. Suppose we have empirical data {(x1, y1), (x2, y2), …, (xn, yn)} that was obtained from some experiment. We have strong reason to believe y is related to x by some smooth function, but we do not know what that function is. We would like to find a function that can be used to approximate values of y for given values of x between the given data points. There are many ways to approach this problem, but the three most common are least squares, Lagrange interpolation, and cubic splines. Each of these methods has advantages and limitations compared to the other two. Includes PDF documentation.

Fractional Base Conversions   (details) 49/50 48 ENG   3 KB / 1 KB
Set of programs that convert between integers and numbers in fractional base. The program I->FBL expects an integer n on level 3, the numerator p on level 2 and the denominator q on level 1. The program returns a list of integers representing the digits of n in base p/q, in standard order (units on the right, highest powers on the left). For example, if the level 3 argument is 15, level 2 is 3 and level 1 is 2, the result is { 2 1 0 1 0}, the digits of 15 in base 3/2.

This program computes the Lerch transcendent Phi(z, s, a). The arguments may be real or complex. The program is a straightforward implementation of the function definition and it converges fairly quickly if |z| is not close to 1. The execution time rises and accuracy decreases as |z| approaches 1, so this is not an efficient algorithm for the Zeta function. The number 9999 for the maximum number of iterations may be lowered to improve speed at the cost of accuracy for values of |z| close to 1.
