The python scipy module scipy.sparse.csr_matrix contains a method toarray() to convert the given matrix into an array. Csr_matrix ( (data, indices, indptr), [shape= (m, n)]) is the standard csr representation where the column indices for row i are stored in indices [indptr [i]:indptr [i+1]] and their corresponding.

Python’s scipy gives tools for creating sparse matrices using multiple data structures, as well as tools for converting a dense matrix to a sparse matrix. Sparsity= (no of zero’s)/ size of the matrix. For more information about how to create a sparse matrix please visit how to create a sparse matrix in python we use the multiply() method provided in both csc_matrix.
