ConvOffs Transform   (details) 49/50 48 ENG   3KB/1KB
Generalizations of the method used to create Pascal's triangle and similar number triangles, containing two programs. The first program takes a list of integers and returns the transformed list, which will be one term longer than the input list. The next program implements the ConvOffsStoT transform. It calls the program above. This program is basically the same but returns a list of lists which are transforms of sublists of the input list. Given a list of length n, the program will return lists of length 1 through n+1.

Cubic Spline System   (details) 49/50 ENG   188KB/4KB
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.
