Hello Ruipeng Li,

thank you for your support, too. Yes, it would be very nice, if you 
could provide me the standalone versions via email, if possible 
(address@hidden or address@hidden). Or are these sources online 
available (e.g. your university homepage)?

I had already a closer look at the online available ITSOL_2 library. Are 
the standalone versions implemented for the modified CSR-format, too? I 
was afraid, that a transposition of input and output matrices will have 
a great impact on the computation time. Do you have some experience with 
this circumstance?

Kind regards,

Kai
