so th equestion is :
is possible to open it than it ask something and it tell me the
result??
thank you!!
p.s.
this is my hessiana.py:
import sympy as S
x,y=S.symbols('xy')
f=x**4+x**2-6*x*y+3*y**2
a=S.diff(f,x)
S.pprint(a)
b=S.diff(f,y)
S.pprint(b)
S.solve_system([a,b],[x,y])
H=S.hessian(f,[x,y])
M1=S.Matrix([14,-6],[-6,6])
M2=S.Matrix([2,-6],[-6,6])
S.Matrix.berkowitz_minors(M2)
S.Matrix.berkowitz_minors(M1)
