numpy.polynomial.chebyshev.Chebyshev.truncate¶
-
Chebyshev.
truncate
(size)¶ Truncate series to length size.
Reduce the Chebyshev 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: size : positive 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_instance : Chebyshev
New instance of Chebyshev with truncated coefficients.
