numpy.polynomial.Polynomial.truncate ¶
method
 Polynomial. truncate ( size ) ¶

Truncate series to length size .
Reduce the series to length size by discarding the high degree terms. The value of size must be a positive integer. This can be useful in least squares where the coefficients of the high degree terms may be very small.
 Parameters

 size positive int

The series is reduced to length size by discarding the high degree terms. The value of size must be a positive integer.
 Returns

 new_series series

New instance of series with truncated coefficients.
