LinearSolve[A,b]??

anonymous · Answer

Kidnap Adam Jensen and Neo, enter the matrix, and confront the Wizard of Math. Be prepared, as you must battle him with quantum mechanical inverse kinematic equations.

still working through it but can you not define an augmented matrix on mathematica?

anonymous · Answer

well I tried Linear Solve[A, {0, 0, y, y}] since A is a 4,4 matrix and it 0 is not a valid variable.
