numpy.polynomial.chebyshev.Chebyshev.cutdeg — NumPy v1.13 Manual (original) (raw)
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: | deg : non-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_series : series New instance of series with reduced degree. |
