-*'''ichol:''' In this case things should be easier at first glance. Kai  implemented the functions related with ichol from Fortran prototypes and they work as expected. In theory would be only necessary to code the complex versions and the modified versions of the algorithms. On the other hand, there is an issue here with licenses I did not know at first and Kai pointed me out (see [http://edu159-gsoc2014.blogspot.com.es/2014/03/introducing-myself.html#bc_0_1B here]). Authors should be contact in order to ask for a permission, but if they are not in favor of giving to us then another strategy will be needed to be set.

 :The road map of what and how I want to do the project is clear to me, but I don't know for sure if it will be enough for the GSoC period. Because I am concerned about that there are other functions that I would like to implement if it would be necessary like '''lsqr''' and '''minres''', both highly related with ichol and ilu. I have already done some search and found that this website [http://www.stanford.edu/group/SOL/software/lsqr/ lsqr] [http://www.stanford.edu/group/SOL/software/minres/ minres]. The website is from the people that wrote the papers given as references in Matlab documentation. In the website there are several codes that can be used. I have mailed professor Michael Saunders about adapting them into Octave versions and he answered me that I am welcome to do while I respect the license (CPL or BSD licenses). He claimed that they are very unrestrictive but I've been told that they are not compatible with GPL3. I will need some insights about that if I happen to have time for implementing them.
+'''Project structure'''
+-------------------------
+These are the main files that will be needed for the project:
+* ilu.m -- Act as a wrapper for the rest of the ilu functions
+** ilu0.cc -- Implements ilu decomposition zero level of fill
+** ilut.cc -- Implements ilu decomposition with threshold
+** iluc.cc -- Implements Crout version of ilu decomposition
+** ilutp.cc-- Implements the ilu decomposition with threshold and pivoting
+*ichol.m -- Act as a wraper for the rest of ichol functions
+** ichol0.cc -- Implements ichol decomposition with zero level of fill
+** icholt.cc -- Implements ichol decomposition with threshold
+** icholt0jp.cc -- Implements ichol decomposition following Jones and Plassmann strategy
+NOTE: All the algorithms could be used with real and complex numbers and "modifified versions" will be implemented as well.

-'''Note:''' I set schedule starting on May 19th but I would like to start coding since I know I am selected (22 April), so maybe goals would be reached before stated above. So that dates should be taken as top limits. In June 3 exams are scheduled that still not have fixed dates. I am not worried about them since I have a lot of time for studying.
