# `CPPMatrixLib` - A Portable Matrix Library in C++
This is a simple matrix library, that is built to have a similar interface for matrices as compared to MATLAB or NumPy. Built as a project for [WnCC SoC '21](https://wncc-iitb.org/soc_projects/118-laxman-matrix.html).
### Proficiency Test: (Deadline: 23rd March 5pm)
1. Fork & clone [CPPMatrixLib](https://github.com/relaxxpls/CPPMatrixLib)
2. Go through [main.cpp](https://github.com/relaxxpls/CPPMatrixLib/blob/main/main.cpp), and try to understand how the functions and operators present.
2. Add a file called as `my_gauss_elim.cpp`
3. Inside your `my_gauss_elim.cpp` file, implement a simple code to convert a given non-singular square matrix into its Row Echelon form (upper triangular matrix), using the [matrix](https://github.com/relaxxpls/CPPMatrixLib/blob/main/matrix.hpp) and [matrix_utility](https://github.com/relaxxpls/CPPMatrixLib/blob/main/matrix_utility.hpp) headers.
4. Finally add a `main` function to your `my_gauss_elim.cpp` that shows your algorithm in action!
**Submission:** Once you’ve finished the test, [mail me](mailto:desai.laxman2001@gmail.com) a link to your repository (containing the `my_gauss_elim.cpp` file).
*If you are unable to complete the test due to lack of time, submit whatever you’ve done!*

### Features:
* lightweight
* dependency-free
* similar functioning to STL
* variety of operators, including matrix-matrix operators and matrix-number operators and a bunch of linear algebra functions
### Updates:
V1.5 Added QR Decomposition and a few usage examples in [main.cpp](https://github.com/relaxxpls/CPPMatrixLib/blob/main/main.cpp)
### Motivation:
I like Linear Algebra, but the scripting nature of MATLAB makes working a pain. Plus it's paid :(
C++ dosent natively support Linear Algebra, and using heavy packages can make running your code on a different device a pain. What if you could just copy paste a few KBs and get most of MATLABS Linear Algebra functionality?
The Big Picture:
- Aim to build a light weight math library.
- Currently work is under way, and a raw polynomial library is ready. It supports FFT and multimod NTT. Once it's style is improved, it will be added here.
- Work is also underway for a primes library, supporting prime tests and factorisation
### Changes Proposed:
* Add iterators (row and column wise) so as to increase compatibility with STL algorithms (search & sort)
* Add a function to calculate the Eigen values and Eigen vectors of a matrix
* Add LU & SVD functions that can help calculate the inverse of a matrix
* Add functionality to solve Linear Equations (A*X = B)
* Add documentation
* Depict its use in solving Linear Recurrences as an example solve [Project Euler 258](https://projecteuler.net/problem=258)
