`Hermite.``truncate`(size)

  Truncate series to length size.

  Reduce the Hermite 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 : Hermite New instance of Hermite with truncated coefficients.
