Fudgit
Multi-purpose data-processing and fitting program
/Main/FreeBSD/6-current/sparc64/FUDGIT is a double-precision multi-purpose fitting program.
It can manipulate complete columns of numbers in the form
of vector arithmetic. FUDGIT is also an expression language
interpreter understanding most of C grammar except pointers.
Morever, FUDGIT is a front end for any plotting program supporting
commands from stdin. It is a nice mathematical complement to
GNUPLOT, for example.
The main features of FUDGIT are:
- Command shell including history;
- Possible abbreviation of all the ``fitting mode'' commands;
- Possible plural when it makes sense too;
- Interactive shell supporting flow control (while,
if-else-endif, foreach);
- User definable macros;
- User definable aliases;
- On-line help;
- On-line loadable procedure- or function-objects;
- On-line selectable plotting program;
- Fourier transforms;
- Spline interpolation;
- Smoothing;
- Double-precision built-in calculator;
- Built-in interpreter supporting most of C language including
flow control (if, else, while, for, break, continue);
- User definable functions and procedures;
- Double-precision vector arithmetic;
- Access to the complete C math library;
- Access to any external C or FORTRAN routines/libraries
through dynamic loading;
- Built-in fitting series such as:
+ power series (polynomial);
+ sine series;
+ cosine series;
+ Legendre polynomials;
+ series of Gaussians;
+ series of exponentials;
+ series of lorentzian;
- User definable fitting functions;
- Totally dynamical allocation of variables and parameters;
- Possible selection of fitting ranges;
FUDGIT has a collection of fitting routines including:
- straight line (linear) least squares;
- straight line (linear) least absolute deviation;
- general linear least squares using QR decomposition;
- general linear least squares using singular value decomposition;
- nonlinear Marquardt-Levenberg method;
