Question

How do you perform basic operations on sparse matrices, such as addition and multiplication?

Answer 1

You can perform basic operations on sparse matrices just like dense matrices. Here's an example of matrix multiplication:

import scipy.sparse as sp

# Create two sparse matrices
matrix1 = sp.csr_matrix([[1, 0], [0, 2]])
matrix2 = sp.csr_matrix([[3, 0], [0, 4]])

# Matrix multiplication
result = matrix1.dot(matrix2)
