I am using a python function called "incidence_matrix(G)", which returns the incident matrix of graph. It is from Networkx package. The problem that I am facing is the return type of this function is "Scipy Sparse Matrix". I need to have the Incident matrix in the format of numpy matrix or array. I was wondering if there is any easy way of doing that or not? Or is there any built-in function that can do this transformation for me or not?
Thanks
The scipy.sparse.*_matrix
has several useful methods, for example, if a
is e.g. scipy.sparse.csr_matrix
:
a.toarray()
- Return a dense ndarray representation of this matrix. (numpy.array
, recommended)a.todense()
- Return a dense matrix representation of this matrix. (numpy.matrix
)Previously, these methods had shorthands (.A
for .toarray()
, and .M
for .todense()
), but these have been or will be deprecated as of Scipy v1.14.0.
