   def     evaluate_nd (    c    ,    xs    ,    ks    ,    xp    ,    dx    ,    extrapolate    ,    out      )

Evaluate a piecewise tensor-product polynomial.

c : ndarray, shape (k_1*...*k_d, m_1*...*m_d, n): Coefficients local polynomials of order k-1 in m_1, ..., m_d intervals. There are n polynomials in each interval.
ks : ndarray of int, shape (d,): Orders of polynomials in each dimension
xs : d-tuple of ndarray of shape (m_d+1,) each: Breakpoints of polynomials
xp : ndarray, shape (r, d): Points to evaluate the piecewise polynomial at.
dx : ndarray of int, shape (d,): Orders of derivative to evaluate. The derivative is evaluated piecewise and may have discontinuities.
extrapolate : int, optional: Whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs.
out : ndarray, shape (r, n): Value of each polynomial at each of the input points. For points outside the span x[0] ... x[-1], nan is returned. This argument is modified in-place.
