Assessment of systems of linear equations and general solution for undetermined systems in Matlab
Very basic assessment of systems of linear equations using Matlab or Octave and finding the general solution for underdetermined systems. For underdetermined systems with less solutions than variables - add row of zeros to the bottom of the augmented matrix or to A and b to get a SQUARE matrix so that the length of the solution vector (x) is equal to the amount of variables in A in Ax=b.
