integrate_1d#
- NdPPoly.integrate_1d(a, b, axis, extrapolate=None)[source]#
- Compute NdPPoly representation for one dimensional definite integral - The result is a piecewise polynomial representing the integral: \[p(y, z, ...) = \int_a^b dx\, p(x, y, z, ...)\]- where the dimension integrated over is specified with the axis parameter. - Parameters:
- a, bfloat
- Lower and upper bound for integration. 
- axisint
- Dimension over which to compute the 1-D integrals 
- extrapolatebool, optional
- Whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs. 
 
- Returns:
- igNdPPoly or array-like
- Definite integral of the piecewise polynomial over [a, b]. If the polynomial was 1D, an array is returned, otherwise, an NdPPoly object.
