numpy.polynomial.polynomial.Polynomial.truncate

method

polynomial.polynomial.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:

sizepositive 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_seriesseries

New instance of series with truncated coefficients.
