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 ofsize
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 ofsize
must be a positive integer.
- Returns
- new_seriesseries
New instance of series with truncated coefficients.
