HermiteE.truncate(size)

numpy.signbit(x[, out]) = Returns element-wise True where signbit is set (less than zero).

numpy.reciprocal(x[, out]) = Return the reciprocal of the argument, element-wise. Calculates 1/x.

Polynomial.deriv(m=1)

Laguerre.trim(tol=0)

numpy.empty_like(a, dtype=None, order='K', subok=True) Return a new array with the same shape and type as a given array.

numpy.ceil(x[, out]) = Return the ceiling of the input, element-wise. The ceil of the scalar x is the smallest

numpy.polynomial.legendre.legone = array([1])

Background The API exposed by NumPy for third-party extensions has grown over years of releases, and has allowed programmers to directly access NumPy functionality from

numpy.ma.atleast_2d(*arys) = View inputs as arrays with at least two dimensions.
