numpy.eye(R, C = None, k = 0, dtype = type <‘float’>) : –The eye tool returns a 2-D array with 1’s as the diagonal and 0’s elsewhere. The diagonal can be main, upper, or lower depending on the optional parameter k. A positive k is for the upper diagonal, a negative k is for the lower, and a 0 k (default) is for the main diagonal.
R : Number of rows C : [optional] Number of columns; By default M = N k : [int, optional, 0 by default] Diagonal we require; k>0 means diagonal above main diagonal or vice versa. dtype : [optional, float(by Default)] Data type of returned array.
array of shape, R x C, an array where all elements are equal to zero, except for the k-th diagonal, whose values are equal to one.
Matrix b : [[ 1. 0.] [ 0. 1.]] Matrix a : [[ 0. 0. 0. 0. 0.] [ 1. 0. 0. 0. 0.] [ 0. 1. 0. 0. 0.] [ 0. 0. 1. 0. 0.]]
