Revision 1228 - (hide annotations) (download) (as text)
Thu Jan 25 06:57:40 2007 UTC (12 years, 9 months ago) by johnpye
Original Path: trunk/test.py
File MIME type: text/x-python
File size: 30543 byte(s)
Added getParameter by name in SolverParameters.
Fixed up refences to signal-related header files.
Fixed up various warnings from -pedantic compilation.
Identified an apparent bug with RelationCalcGradient (unsafe version).
Added support for compilation of a standalone C++ program (idatest) in SCons build.
