Isalathiso seSciPy sparse matrix enoluhlu lweebooleans

i-NumPy arrays inokufakwa kwisalathiso ngee-booleans ukukhetha imiqolo ehambelana Yinyani amangeno:

>>> X = np.array([[1,2,3], [4,5,6], [7,8,9]])
>>> rows = np.array([True,False,True])
>>> X[rows]
array([[1, 2, 3],
       [7, 8, 9]])
>>> X[np.logical_not(rows)]
array([[4, 5, 6]])

Kodwa oku kubonakala ngathi akunakwenzeka ngeSciPy imatriki ezinqabileyo; ii-indices zithathwa njengamanani, ke Ubuxoki khetha umqolo 0 kunye Yinyani ukhetha umqolo 1. Ndingayifumana njani indlela yokuziphatha kweNumPy? 11121441]
