I have placed a curve fitting program on Hobbes. ParamBSpline2: A program to generate a smooth curve from sequential points in n-dimensional data. It can be
used to:
Smooth a set of data
Insert additional points between existing points
Reduce the number of data points
Obtain estimates at fixed intervals
Obtain estimates at specified points.
This is a program of use to scientists, engineers and others who must modeldata. The program does not suffer from the most common limitations of curve fitting
programs. For example:
The data values do not need to satisfy a monotonicity requirement. In other words a given X may have more than one Y value. See the illustration in the zip file.
The closeness of fit is controllable several ways. Ouput spacing is flexible. The program is operating system independent. It uses only ANSII standard REXX.
Documentation in OS/2 and .html formats are provided. The highly commented and the source code is included in the package.
