Subject: Fortran To Java



Has anyone in this list ever used  F2J  tool  (fortran2java) for code 
generation of fortran into java ?  I have ported some free Matlab 
machine learning  codes for LLE (Locally Linear Embedding) found on the 
internet into Java using JAMA , however I am not sure whether there 
would be a big difference in using  Matlab  'eig'  and  'eigs' .  The 
original  Matlab LLE  codes  uses  'eigs' command  , but  I know that  
JAMA's   EigenDecomposition class is the equivalent of  the Matlab 
command  'eig' , so my Java LLE is not quite an exact porting of the 
original  LLE, since  JAMA doesn't have the equivalent  'eigs'.  Matlab 
'eigs' uses  the fortran  ARPACK and I may be looking at using the  F2J 
tool to convert  ARPACK into Java.  I wondered how accuracy is this  F2J 
tool is whether it will give a reliable fortran to java conversion that 
does not create bugs in the process.  Anyone here who has used  F2J who 
can make a comment, please ?

Cheers,
Sione.
