ZOOM CLHEP Generic Functions Package Release Notes

5/15/03

CLHEP v1.9.0, cvs rtag V01-09-00

GenericFunctions
PtRelFcn now includes <float.h> to overcome a compilation error

4/4/03

CLHEP v1.8.3, cvs rtag V01-08-03

GenericFunctions
Elimination of MetaProxy scheme
Finally got rid of the MetaProxy scheme in favor of something much simpler: putting all the code that calls gsl into .icc files. That makes CLHEP independent of the external package. (User code that includes Bessels, Spherical Bessels/Neumanns, or Elliptic Integral functions will develop a dependency on the gsl package.)
New functions:
Logistic equation
Function accumulators
PtRel function
Runge Kutte Integrators
with an adaptive stepsize algorithm, to integrate N first-order autonomous differential equations

10/28/02

CLHEP v1.8.2, cvs rtag V01-08-02

GenericFunctions
ParamToArgAdaptor.icc
removed use of numeric_limits class, use of which limits portability
Correct a warning about double to int
caused by using a 1.0 in an expression being used as int argument to factorial in Psi2hydrogen.

7/24/02

CLHEP v1.8, cvs rtag V01-08-00

GenericFunctions
New Genfunction Psi2Hydrogen for hydrogenic wavefunction
Added an Absolute Value function
Generic functions to use all-include file for wrappered routines
This pushes responsibility of finding gsl onto the user, but allows building of the CLHEP library (especially in the ZOOM context) to go much more rapidly.

4/23/02

CLHEP v1.7.12, cvs rtag V01-07-12

GenericFunctions
Fixed warnings for GCC 3 coming from IncompleteGamma.
Previous attempts to fix this had introduced an error which in some cases could cause the routine to hang. This is corrected.

12/21/01

CLHEP v1.7.7, cvs rtag V01-07-07

GenericFunctions
Compilation of the gsl C code removed from GNUmakefile.
There is now available a kit (installable via ups/upd and so forth) containing the Gnue Scientific Library special functions.
The kit is called gsl, and may be installed via upd.
To link the library in, setup gsl , and find the library under $GSL_DIR as for any ups product.
This makes for significantly shorter intial builds of CLHEP, and also corrects a situation on some combinations of platform and build options where the build of the C code for gsl was wiping out the remainder of the C++ modules from the CLHEP library.

10/19/01

CLHEP v1.7.3, cvs rtag V01-07-03

GenericFunctions
Added elliptic integrals

1/22/01

CLHEP v1.6.1, cvs rtag V01-06-01

Added new package - GenericFunctions
Function objects which represent a wide spectrum of functions and may be combined and manipulated according to the rules of function composition.
