Matrix_h hosts a fast, efficient and easy to use C linear algebra library

Libmatrix

Libmatrix is a fast, efficient and easy to use C linear algerbra library.

MOTIVATION

This project was started to develop a linear algebra library written in the C programming language that is simple and easy to use without reducing the performance of the code

KEY FEATURES

• Simple and easy to use
• Fast and memory efficient
• No explicit pointers
• Error detection

INSTALLATION

Clone the repository into your computer by executing the following command in the terminal

git clone https://github.com/prithvitewatia/matrix_h

cd in the the repository

cd matrix_h

Run the following command

make libmatrix.a

If everything runs fine you will see files libmatrix.a and matrix.o generated in the directory. If not please make sure that you have gcc and make installed and set on the PATH. Link to
gcc: gcc
make: make

Congrats your library is now generated

Usage

• Copy the matrix.h file and libmatrix.a to your project folder.
• Include the library in your C file by using the include directive

#include "matrix.h"

• To build your C file execute the command

gcc yourCfile.c  -L . -lmatrix -o yourOutputfile

• Run your file by

./yourOutputfile

Happy coding!

EXAMPLES

A program to add to matrices and check if the result is equal to third matrix.

The output of the above program

Here is another example in which we calculate rank and determinant.

Here is its output

CAUTION

• If x and y are two matrices do not use statements such as x=y to copy the contents of y into x. Rather use x=copy_matrix(y) to copy the contents. This is because statement x=y will make the references of x and y same and hence further changes in y will lead to changes in x.
• Also since floating point numbers are not infinitely precise therefore ieee has two representation of number 0 ie 0 and -0 . This is not a bug. This is just a way of representation in which no information is lost.

matrix_h's Issues

Write tests for function copy_matrix

we need to write tests for copy_matrix function.

Add tests for function submatrix

Write tests for set_value on out of bounds

The function set_value is not tested on out of bounds. Write death tests similar to tests of function new_matrix

Write tests for get_value on out of bounds

The function get value is not tested for out of bounds on column and row. Write a death test similar to new_matrix.

Add tests for function matrix_dot
