I am an undergraduate 4th year Computer Science student at Guru Nanak Dev Engineering College, Ludhiana. I have formidable learning in C++, PHP and MySQL. I have a strong affinity for Mathematics which keeps my inquisitiveness alive for learning more about numerical functions and their implementation through programming.

=== 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.
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.


=== Introduction to Project ===
=== Your task ===
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.
* Did you select a task from our list of proposals and ideas?


=== Synopsis ===
''yes''
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.


== Detail Project Timeline ==
** If yes, what task did you choose? Please describe what part of it you especially want to focus on if you can already provide this information.

    Getting familiar with the code
* Please provide a rough estimated timeline for your work on the task.
    Interaction with mentors and the community members


1st week (25th May - 30th May)
GSoC Application period


    Designing the algorithm for calculation of left eigenvectors
'' 'quadprog' wrapper around 'qp' ''


2nd week (1st June - 7th June)
'' 'lsqlin' wrapper around 'qp' ''


    Implementation of the algorithm
Start of GSoC (May)


3rd week (8th June - 14th June)
'' 'lsqnonlin' wrapper around 'nonlin_residmin' ''


    Implementation of calling form for calculating left eigenvectors as third output
'' 'lsqcurvefit' wrapper around 'nonlin_curvefit', 'nonlin_residmin', or 'lsqnonlin', ''


4th week (15th June - 21th June)
'' 'fmincon' wrapper around 'nonlin_min', ''


    Studying Cholesky Factorisation algorithm and QR algorithm
Midterm


5th week (22nd June - 28th June)
instead of wrappers for top-level functions like qp. Call back-end function (__qp__) to be able to extract lambda.


    Implementation of the calling form to choose among generalised algorithms
See [http://octave.1599824.n4.nabble.com/GSoC-2015-Optimization-Package-Non-linear-and-constrained-least-squares-lsqcurvefit-lsqlin-lsqnonlin-tp4668777p4669284.html]


Mid-Term Evaluation
Stretch Goals
Implement another back-end algorithm/add variant.


    Calling form of eig to calculate left eigenvectors as third output
    Calling form for choosing among generalised eigenvalue algorithms


7th week (6th July - 12th July)


    Understanding the concept of balancing


8th week (13th July - 19th July)
=== 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.


    Implementation of algorithm for balancing option
=== 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.


9th week (20th July - 26th July)
=== Present state of project ===
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.


    Implementation of calling form for preliminary balancing
=== Project partition ===
 
Based on the different file formats I will be working on my project will be partioned in the following three parts:-
10th week ( 27th July - 2nd August)
AndroidXML
 
QT ts
    Writing test cases for these calling forms of eig function
JSON
 
11th and 12th week(3rd August - 16th August)
 
  Documentation for the code
  Reviewing the code
  Final touches to the code

Till mid of May, I would be having my final exams. But after that I would be completely free to devote all my time to GSoC. So I will be comfortably able to manage to fulfill my tasks within the specified time.

== Objective of joining GNU ==
== Objective of joining GNU Octave ==
 
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.
I have been using stupendous products of GNU organisation from the very starting point of my career in open source world. I have been a regular user of GNU Bison, gdb, gcc etc. GNU Octave being a project which touches my area of interest. So, it would be a great honor for me to be a part of such a cardinal community and ameliorate myself in the field of programming and mathematics.


== Why me? ==
== Why me? ==
 
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.
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.
