numpy.polynomial.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.
