`scipy.interpolate._ppoly:integrate`

Signature

def integrate(c, x, a, b, extrapolate, out)

Compute integral over a piecewise polynomial.

c : ndarray, shape (k, m, n): Coefficients local polynomials of order k-1 in m intervals.
x : ndarray, shape (m+1,): Breakpoints of polynomials
a : double: Start point of integration.
b : double: End point of integration.
extrapolate : bint, optional: Whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs.
out : ndarray, shape (n,): Integral of the piecewise polynomial, assuming the polynomial is zero outside the range (x[0], x[-1]). This argument is modified in-place.
