Return a 2-D array with ones on the diagonal and zeros elsewhere.
Number of rows in the output.
Number of columns in the output. If None, defaults to N.
Index of the diagonal: 0 (the default) refers to the main diagonal,
a positive value refers to an upper diagonal, and a negative value
to a lower diagonal.
Data-type of the returned array.
Whether the output should be stored in row-major (C-style) or
column-major (Fortran-style) order in memory.
New in version 1.14.0.
Reference object to allow the creation of arrays which are not
NumPy arrays. If an array-like passed in as like supports
the __array_function__ protocol, the result will be defined
by it. In this case, it ensures the creation of an array object
compatible with that passed in via this argument.
The like keyword is an experimental feature pending on
acceptance of NEP 35.
New in version 1.20.0.
An array where all elements are equal to zero, except for the k-th
diagonal, whose values are equal to one.
(almost) equivalent function
diagonal 2-D array from a 1-D array specified by the user.
>>> np.eye(2, dtype=int)
>>> np.eye(3, k=1)

[0., 0., 1.],
[0., 0., 0.]])
