numpy.matmul(a, b, out=None) Matrix product of two arrays. The behavior depends on the arguments in the following way.

numpy.polysub(a1, a2)

MaskedArray.__len__() <==> len(x)

numpy.core.defchararray.greater_equal(x1, x2)

MaskedArray.__rlshift__ x.__rlshift__(y) <==> y<<x

numpy.triu_indices(n, k=0, m=None)

numpy.ptp(a, axis=None, out=None)

record.pprint()

chararray.istitle()

numpy.ma.compress_rowcols(x, axis=None)
