Dear author, I cannot understand the representation of system of polynomials in test/nonlineq.py
Plz make me understand. Thanks in advance
""" Solve the system y^2 - x*y = 4, x^2 - xy = -3, which has solutions
(-3,-4) and (3,4).
"""
f = lambda y: array([[y[1,0]*y[1,0] - y[0,0]*y[1,0] - 4.0],
[y[0,0]*y[0,0] - y[0,0]*y[1,0] + 3.0]])
