dask.array.eye(N, chunks='auto', M=None, k=0, dtype=<class 'float'>)[source]

Return a 2-D Array with ones on the diagonal and zeros elsewhere.


Number of rows in the output.

chunksint, str

How to chunk the array. Must be one of the following forms:

  • A blocksize like 1000.

  • A size in bytes, like “100 MiB” which will choose a uniform block-like shape

  • The word “auto” which acts like the above, but uses a configuration value array.chunk-size for the chunk size

Mint, optional

Number of columns in the output. If None, defaults to N.

kint, 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.

dtypedata-type, optional

Data-type of the returned array.

IArray of shape (N,M)

An array where all elements are equal to zero, except for the k-th diagonal, whose values are equal to one.
