scipy.interpolate.PPoly.
extend#
- PPoly.extend(c, x)[source]#
- Add additional breakpoints and coefficients to the polynomial. - Parameters:
- cndarray, size (k, m, …)
- Additional coefficients for polynomials in intervals. Note that the first additional interval will be formed using one of the - self.xend points.
- xndarray, size (m,)
- Additional breakpoints. Must be sorted in the same order as - self.xand either to the right or to the left of the current breakpoints.
 
 - Notes - This method is not thread safe and must not be executed concurrently with other methods available in this class. Doing so may cause unexpected errors or numerical output mismatches.
