    Plotting could be solved with vectors but I'm not sure about plotting them as points and not in a straight line. Hard to read out the minimum value without seeing if there is an actual point or not...

    Ok so I decided to completly re-organize my project! Why? Because it all comes down to the Gaussian elimination with or without pivoting and in that case it's more comfortable to have it all running with each other and having the pivoting stuff as an secondary option inside of the function. Also the output is simplified by just giving you the result and the matrices are now saved compact inside of A. forward substitution: Source Code (22 lines) backward substitution: Source Code (28 lines) LU de…
