# Algebraic Linear Equations

This script allows you to run a linear equations solver using eval and built-in complex numbers.One could add one more line to insert '*' where needed, i.e. "100x" -> "100*x", add some input validation, in particular check whether the equation is actually linear and not quadratic or cubic, and...

This code can be used to solve a set of linear equations using Gaussian elimination with partial pivoting. Note that the Augmented matrix rows are not directly switches. Instead a buffer vector is keeping track of the switches made. The final solution is determined using backward substitution.
