scipy.sparse.
find#
- scipy.sparse.find(A)[source]#
- Return the indices and values of the nonzero elements of a matrix - Parameters:
- Adense or sparse array or matrix
- Matrix whose nonzero elements are desired. 
 
- Returns:
- (I,J,V)tuple of arrays
- I,J, and V contain the row indices, column indices, and values of the nonzero entries. 
 
 - Examples - >>> from scipy.sparse import csr_array, find >>> A = csr_array([[7.0, 8.0, 0],[0, 0, 9.0]]) >>> find(A) (array([0, 0, 1], dtype=int32), array([0, 1, 2], dtype=int32), array([ 7., 8., 9.]))
