Signature

def evaluate ( c , x , xp , dx , extrapolate , out )

Evaluate a piecewise polynomial.

c : ndarray, shape (k, m, n): Coefficients local polynomials of order k-1 in m intervals. There are n polynomials in each interval. Coefficient of highest order-term comes first.
x : ndarray, shape (m+1,): Breakpoints of polynomials.
xp : ndarray, shape (r,): Points to evaluate the piecewise polynomial at.
dx : int: Order of derivative to evaluate. The derivative is evaluated piecewise and may have discontinuities.
extrapolate : bint: 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. This argument is modified in-place.
