numpy.polynomial.chebyshev.Chebyshev.trim¶
- Chebyshev.trim(tol=0)[source]¶
Remove trailing coefficients
Remove trailing coefficients until a coefficient is reached whose absolute value greater than tol or the beginning of the series is reached. If all the coefficients would be removed the series is set to [0]. A new series instance is returned with the new coefficients. The current instance remains unchanged.
Parameters: tol : non-negative number.
All trailing coefficients less than tol will be removed.
Returns: new_series : series
Contains the new set of coefficients.
