::I have been in contact with Kai by mail and agrees that writing from scratch all the functions needed as oct-files (ILUTP, ILU0, ILUC and ILUT) would be a harder but safer way to go if integration want to be achieved. This way no dependencies are needed to be added and the overhead of translating the data from Octave to ITSOL and vice verse is eliminated. Algorithms will be taken from Yousef Saad's book "Iterative methods for sparse linear systems Ed. 2". Moreover, I can use some of the code that Kai wrote, mostly the tests, documentation and the m-file "ilu.m" that glue together all the functions. ITSOL source code is also a good place to look for some help. | ::I have been in contact with Kai by mail and agrees that writing from scratch all the functions needed as oct-files (ILUTP, ILU0, ILUC and ILUT) would be a harder but safer way to go if integration want to be achieved.
