numpy.identity(n, dtype = None) : Return a identity matrix i.e. a square matrix with ones on the main daignol.
n : [int] Dimension n x n of output array dtype : [optional, float(by Default)] Data type of returned array.
identity array of dimension n x n, with its main diagonal set to one, and all other elements 0.
# Python Programming illustrating # numpy.identity method import numpy as geek # 2x2 matrix with 1's on main diagnol b = geek.identity(2, dtype = float) print("Matrix b : \n", b) a = geek.identity(4) print("\nMatrix a : \n", a)
Matrix b : [[ 1. 0.] [ 0. 1.]] Matrix a : [[ 1. 0. 0. 0.] [ 0. 1. 0. 0.] [ 0. 0. 1. 0.] [ 0. 0. 0. 1.]]
