With the help of sympy.Matrix.eigenvals() method, we can find the eigen values of the matrix.

Syntax : sympy.Matrix().eigenvals() 
Return : Return the eigen values of a matrix. 
 

Example #1 : 

In the given example we can see that the sympy.Matrix.eigenvals() method is used to find the eigen values of a matrix.  

Python3




# Import all the methods from sympy
from sympy import *
 
# use the eigenvals() method for matrix
gfg_val = Matrix([[1, 2], [2, 1]]).eigenvals()
 
print(gfg_val)


Output :

{3: 1, -1: 1} 
 

Example #2 :

Python3




from sympy import *
 
# use the eigenvals() method for matrix
gfg_val = Matrix([[1, 2], [2, 2]]).eigenvals()
 
print(gfg_val)


Output :

{3/2 – sqrt(17)/2: 1, 3/2 + sqrt(17)/2: 1}
