ParametersReturns
eye(N, chunks='auto', M=None, k=0, dtype=<class 'float'>)

Parameters

N : int

Number of rows in the output.

chunks : int, 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

M : int, optional

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

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.

dtype : data-type, optional

Data-type of the returned array.

Returns

I : Array 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.

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

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
