Row Division in Scipy Sparse Matrix

Question

I want to divide a sparse matrix\'s rows by scalars given in an array.

For example, I have a csr_matrix C :

C = [[2,4,6], [5,         


        

Answer 1

one line code: result = [[C[i][j]/D[i] for j in range(len(C[0]))] for i in range(len(D))]

C = [[2,4,6], [5,10,15]] #len(C[0]) = 3
D = [2,5] # len(D) = 2
result = [[C[i][j]/D[i] for j in range(len(C[0]))] for i in range(len(D))]
print result
