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.

Web site.
