<P><FONT SIZE=2>Hi All :<BR>
<BR>
I compiled ipopt 3.4.1, ran a problem but have some error in IPOPT.OUT as below:<BR>
<BR>
<BR>
Exception of type: UNKNOWN_MATRIX_TYPE in file "ipopt/IpTripletHelper.cpp" at line 95<BR>
<BR>
:<BR>
<BR>
Exception message: Unknown matrix type passed to TripletHelper::GetNumberEntries<BR>
<BR>
<BR>
<BR>
EXIT: Some uncaught Ipopt exception encountered.<BR>
<BR>
<BR>
Can anyone give some suggestions to fix? I believe this is a machine related problem.<BR>
<BR>
Thanks,<BR>
<BR>
