Revision 1133 - (hide annotations) (download) (as text)
Sun Jan 14 11:51:48 2007 UTC (15 years, 7 months ago) by johnpye
File MIME type: text/x-python
File size: 25275 byte(s)
Removed the 'REX' and 'IEX' array aliases (added the solver parameter comments directly in the slv_param_* calls).
Renamed Simulation::[gs]etSolverParameters to Simulation::[gs]etParameters.
Added [gs]etParameter (singular) methods to SWIG wrapper.
Fixed missing NULL in IDA.
Fixed bug with BDF/AM wrong way round in LSODE.
Removed some debug output from slv.c
