EXPHER - Package for experimental data treatment

home    software section

Expher is a compiler which generates a Fortran 77 program to perform data reduction, error analysis, and all that kind of things.

You give EXPHER a source file where

you state your unknowns
you state your mathematical definitions
you describe what are your measurements (tens, hundreds, arrays, etc.)
you describe your expected experimental errors
you describe what measurements are 'expected' according to your... unknowns

EXPHER generates a Fortran 77 program which answers most questions, giving you the most likely values of your unknowns, their error bars, and the final error matrix. Note that is not limited to the linear unknowns of classical least squares, but it can handle sophisticated (but continuous) functions...

This takes a few hours to be do, while building the same program from scratch takes several months... Try it.

Documentation is available by anonymous ftp at hprib.lps.u-psud.fr, in directories pub/expher/doc/english and pub/expher/doc/french in the form of PostScript files (*.ps), PCL files (*.lj), TeX files and DVI files.

Distribution by anonymous ftp of the programme in directories pub/expher/.... where .... may be unxsun (SUNos), unxaix (RS6000/AIX), unxymp(Cray/UNICOS), unx_hp(HP9000/HP_UX) and vaxvms. Generic distribution in pub/expher/master.

There is also a version of EXPHER which runs under DOS using the f2c and GNU-C compilers. The following restrictions apply:

needs 10 MB of disk space (including the gcc + f2c + libraries)
386 at very least with 4MB of main memory
4MB scratch disk space for execution

Freeware but please cite the work in any publication.
