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.
# import sympy from sympy import *Â Â # Use sympy.eye() method mat = eye(3) Â Â Â print(mat) |
Output :
Matrix([
[1, 0, 0],
[0, 1, 0],
[0, 0, 1]])
Example #2 :
# import sympy from sympy import *Â Â # Use sympy.eye() method mat = eye(5) Â Â Â 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]])
