Linear equations solver

A not-very-fancy linear equations solver.

See https://en.wikipedia.org/wiki/Gaussian_elimination for Gauss-Jordan's algorithm and its uses for solving systems of linear equations.

Compiling

Use the make command to compile the program. The default compiler is GCC.

$ make
$ ./lineqsolve

Input format

In the file matrix.txt are entered the integers coefficients of the matrixes separated by a single space (and none at the end of the lines). On each line are the coefficients and the constant (result), creating in the end one more column than there are lines.

The following system of equations

 x + 2y &= 3\\
4x + 5y &= 6

would be represented in the text file as:

1 2 3
4 5 6

Documentation

The code is documented using Doxygen's format. The documentation can be generated with the command:

$ doxygen Doxyfile
