Polynomial.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.
