A calculator, featuring algorithms from Linear Algebra 1 and Numerical Algorithms

This is a linear algebra calculator, written solely in C

Made in my spare time, to help me do calculations in Linear Algebra 1;
this code showcases formulas and algorithms that were leraned throughout the course.
it was later expended to showcase algorithms and decompositions from Numerical Algorithms.

It has 4 modes:

1. Single matrix operations: Finding reduced row echelon form, rank, determinant, inverse matrix and adjoint matrix (if they exist). Also, finding LU, LDV and QR decompositions; as well as the Frobenius norm of the matrix
2. System of equations solver: Solving a system of equations, using Least Squares (and utilizing QR decomposition to do it)
   *An older version of this calculator used Cramer's rule.
3. Matrix multiplication: Multiplying 2 matrices
4. Convolution: Finding the linear and circular convolution of 2 vectors

It utilizes Windows' API to enable ANSI escape sequences (thus, enabling colored printing)
