polynomial.laguerre.Laguerre.trim(tol=0)

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.

參數:

tolnon-negative number.

All trailing coefficients less than tol will be removed.

回傳值:

new_seriesseries

New instance of series with trimmed coefficients.
