Legendre.truncate(size)[source]¶ Truncate series to length size.
Reduce the 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_series : series
New instance of series with truncated coefficients.
