numpy.polynomial.chebyshev.Chebyshev.cutdeg#
method
- polynomial.chebyshev.Chebyshev.cutdeg(deg)[source]#
Truncate series to the given degree.
Reduce the degree of the series to deg by discarding the high order terms. If deg is greater than the current degree a copy of the current series is returned. This can be useful in least squares where the coefficients of the high degree terms may be very small.
New in version 1.5.0.
- Parameters
- degnon-negative int
The series is reduced to degree deg by discarding the high order terms. The value of deg must be a non-negative integer.
- Returns
- new_seriesseries
New instance of series with reduced degree.
