Python | sympy.eye() method

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. Python3 1=1

# 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 : Python3 1=1

# 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]])
