Right now, I'm just using x = A\b; but I wonder would I get a faster way to solve this system if I do it manually? Any suggestions are very much appreciated. > > Sam
Hello,
If you want to resolve manually Ax=b, there are some methods presented in this book Numerical Methods in Engineering with MATLAB  Jaan Kiusalaas.
