How do I transform a "SciPy sparse matrix" to a "NumPy matrix"?


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


Solution

  • The scipy.sparse.*_matrix has several useful methods, for example, if a is e.g. scipy.sparse.csr_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.
