Laguerre.
fromroots
(roots, domain=[-1, 1], window=[-1, 1])¶ Return Laguerre instance with specified roots.
Returns an instance of Laguerre representing the product
(x - r[0])*(x - r[1])*...*(x - r[n-1])
, wherer
is the list of roots.Parameters: roots : array_like
List of roots.
domain : {array_like, None}, optional
Domain for the resulting instance of Laguerre. If none the domain is the interval from the smallest root to the largest. The default is [-1,1].
window : array_like, optional
Window for the resulting instance of Laguerre. The default value is [-1,1].
Returns: object : Laguerre instance
Series with the specified roots.
