With the help of sympy.eye() method, we can find the identity matrix by using sympy.eye() method.
Syntax : sympy.eye() Return : Return an identity matrix.
Example #1 : In this example, we can see that by using sympy.eye() method, we are able to find identity matrix having dimension nxn, where n will be pass as a parameter.
# import sympy
from sympy import *
  
# Use sympy.eye() method
mat = eye(3)
   
print(mat)

                    
Output :
Matrix([ [1, 0, 0], [0, 1, 0], [0, 0, 1]])
Example #2 :
# import sympy
from sympy import *
  
# Use sympy.eye() method
mat = eye(5)
   
print(mat)

                    
Output :
Matrix([ [1, 0, 0, 0, 0], [0, 1, 0, 0, 0], [0, 0, 1, 0, 0], [0, 0, 0, 1, 0], [0, 0, 0, 0, 1]])
