Test whether all matrix elements along a given axis evaluate to True.
Parameters:See `numpy.all` for complete descriptionsNotes
This is the same as
, but it returns a
object.
Examples
>>> x=np.matrix(np.arange(12).reshape((3,4)));xmatrix([[ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11]])>>> y=x[0];ymatrix([[0, 1, 2, 3]])>>> (x==y)matrix([[ True, True, True, True], [False, False, False, False], [False, False, False, False]])>>> (x==y).all()False>>> (x==y).all(0)matrix([[False, False, False, False]])>>> (x==y).all(1)matrix([[ True], [False], [False]])
