WebFeb 7, 2024 · EDIT: Completely different idea - we can define consistency based on the rank of matrix. If the ranks of augmented matrix and coefficient matrix are same, we can say that the system is consistent. Since numpy is already being used, we can directly find the ranks of both matrices with numpy.linalg.matrix_rank method and return the result. WebSep 16, 2024 · Theorem 1.5.1: Rank and Solutions to a Homogeneous System. Let A be the m × n coefficient matrix corresponding to a homogeneous system of equations, and suppose A has rank r.
