Rref in sympy

WebSymPy is a Python library for symbolic mathematics. It aims to be an alternative to systems such as Mathematica or Maple while keeping the code as simple as possible and easily extensible. SymPy is written entirely in Python and does not require any external libraries. Webcorresponding to the RREF is x 1 = 11, x 2 = 4, x 3 = 3. The equations are already solved for the leading variables. The system has the one solution (11; 4;3). Example. Suppose that the RREF of the augmented matrix of a linear system is 2 4 1 0 1 1 3 0 1 0 2 1 0 0 0 0 0 3 5: The corresponding system is x 1 + x 3 + x 4 = 3 x 2 + 2x 4 = 1: The ...
