mindspore.numpy.eye
- mindspore.numpy.eye(N, M=None, k=0, dtype=mstype.float32)[source]
Returns a 2-D tensor with ones on the diagonal and zeros elsewhere.
- Parameters
N (int) – Number of rows in the output, must be larger than 0.
M (int, optional) – Number of columns in the output. If is
None
, defaults to N, if defined, must be larger than 0. Deault isNone
.k (int, optional) – 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. Default is 0.
dtype (Union[
mindspore.dtype
, str], optional) – Designated tensor dtype. Default is mstype.float32.
- Returns
A tensor of shape (N, M). A tensor where all elements are equal to zero, except for the k-th diagonal, whose values are equal to one.
- Raises
TypeError – If input arguments have types not specified above.
