Mathematics library for C and C++

Follows this tutorial playlist on YouTube.

Description

This is a mathematics library for C and C++ that implements common mathematical concepts and ideas from algebra, calculus, statistics, and linear algebra. A complete list of implemented functions and concepts can be found here.

List of implemented concepts so far:

Data

1. Encryption
   1. AES
2. Hashing
   1. SHA1/SHA2/SHA3
   2. HMAC-SHA, PBKDF2-HMAC-SHA

Graph

1. Graph representation
2. Graph algorithms - Dijkstra, Ford Fulkerson

Linear Algebra

1. Vectors
2. Matrices

Utility

1. Big Integers
2. Expression evaluation

Documentation

Full documentation can be found in the header files in the cmathematics folder.

Use

Simply drag the cmathematics folder into your C or C++ project, not the include directory, and it can be used as if it were apart of the project.

Example file structure:

PROJECT_DIR \
    ...
    cmathematics \
    	cmathematics.h
        ...
    ...
    main.c

Sample use in main.c:

#include "cmathematics/cmathematics.h"
#include "cmathematics/linalg/vec.h"

int main() {
    vec v1 = vector(2.0f, 1.0f, 3.4f);
    printVec(v1);
    
    return 0;
}
