grapharray.classes.AdjacencyMatrix

class grapharray.classes.AdjacencyMatrix(weight: grapharray.classes.EdgeArray, sparse_format: str = 'csr')

N x N matrix

__init__(weight: grapharray.classes.EdgeArray, sparse_format: str = 'csr')

Create a matrix

Parameters

• weight – the element values of the matrix. The value of weight[init, term] is set to the (init, term) element of the matrix.

• sparse_format – str in {‘bsr’, ‘csr’, ‘csc’, ‘coo’, ‘lil’, ‘dia’,

• ‘dok’} –

• matrix. (the format of the sparse) –

Methods

__init__(weight[, sparse_format])

Create a matrix
