== Interested project ==
Because of my affinity for mathematics, I have my keen interest in 'Generalised_eigenvalue_problem' project [http://wiki.octave.org/Summer_of_Code_Project_Ideas#Generalised_eigenvalue_problem]. I want to explore myself more in the field of matrices.

=== Interested project ===
Because of my affinity for mathematics, I have my keen interest in [http://wiki.octave.org/Summer_of_Code_Project_Ideas#Generalised_eigenvalue_problem Generalised_eigenvalue_problem] project and would like to explore myself in the field of matrices.


=== Introduction to Project ===
=== Introduction to Project ===
This project deals with the file conversion of various file formats. The Translate extension has been developed for this purpose. The extension is made supportive for various file formats but the work for only specific format of the input files. The data is read from the input file and stored in the arrays (in the form of key-value pair for JSON file format) and then written in the output file following the file format specifications of the output file format.
This project deals with the [http://in.mathworks.com/help/matlab/ref/eig.html?searchHighlight=eig eig] function in GNU Octave, which calculates the eigenvalues and eigenvectors of a matrix.


=== Synopsis ===
=== Synopsis ===
This project will make the extension robust so that it can handle even the exceptional cases of the input file format. Moreover, a proper documentation will be maintained for the different file formats. I will be mainly focusing on AndroidXML, Qt ts and JSON file formats.
This project will implement missing calling forms of the eig function, which includes preliminary balancing, calculating left eigenvectors as a third ouput and choosing among the generalized eigenvalue algorithms.


=== Present state of project ===
== Detail Project Timeline ==
After carrying out the scrutiny of present working code I found the following limitations:- Lack of proper documentations, unable to handle abnormal cases, only specific format of input file is translated, lack of robust programming and code is not secure.


=== Project partition ===
Based on the different file formats I will be working on my project will be partioned in the following three parts:-
AndroidXML

== Objective of joining GNU Octave ==
Mid-Term Evaluation
As I loved the very concept of open source development from the moment I learned about it, it would be a matter of honour for me to be a part of such a splendid crew. Also I have a firm belief that I will excel tremendously in my area of interest and nurture my skills by working ardently. GNU Octave being an paradigm of its field enticed me to work with it and learn manifold new things.


== Why me? ==
    Calling form of eig to calculate left eigenvectors as third output
Being highly assiduous and fervent for my work I would love to contribute to the open source development since it is like a holy grail to me. I had been into coding environment from quite a time and I wish to apply my whole coding-impetus to a point. I have joined the octave-maintainers@gnu.org mailing list and #octave channel on IRC a few days ago and I am feeling good to interact there and I have already got some valuable suggestions. This is the real blessing for the young saplings in the garden of programming to grow in the guidance of the sublime mentors. I am so much self-obliged and excited to work with dexterous developers across the globe and be a part of the legacy.

Stretch Goals
Because of my keen interest of contributing to the open source world and Octave being the most suitable community for me, I would like to put all sincere efforts to complete my project within the time period. I have joined octave-maintainers@gnu.org mailing list and #octave channel on IRC a few days ago and feeling great to interact with the community members and also I have got worthy feedback from them. Also, I have a good experience with C++ and mathematics always being one of my favorites, I think I am suitable according to the requirements of the project.
