numpy.polynomial.polynomial.Polynomial.truncate¶

method

polynomial.polynomial.Polynomial.truncate(size)[source]¶

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.
