someone can help me?
when I run this script It gave me this error
"C:\Documents and Settings\Proprietario\D
esktop\hessiana.py"
3
-6*y + 2*x + 4*x
-6*x + 6*y
Traceback (most recent call last):
File "C:\Documents and Settings\Proprietario\Desktop\hessiana.py",
line 8, in
<module>
S.solve_system([a,b],[x,y])
AttributeError: 'module' object has no attribute 'solve_system'
this is hessiana.py:
import sympy
x, y = sympy.symbols('xy')
f = x**4 + x**2 - 6*x*y + 3*y**2
a = sympy.diff(f, x)
sympy.pprint(a)
b = sympy.diff(f, y)
sympy.pprint(b)
sympy.solve_system([a,b], [x,y])
H = sympy.hessian(f, [x,y])
M1 = sympy.Matrix([14,-6], [-6,6])
M2 = sympy.Matrix([2,-6], [-6,6])
sympy.Matrix.berkowitz_minors(M2)
sympy.Matrix.berkowitz_minors(M1)
