laguerre( n , z )

The Laguerre polynomial of z in SageMath. Defined by

\[ L_n(z) = \frac{ 1 }{ n! } e^z \frac{ d^n }{ dz^n } ( z^n e^{-z} ) \]

A solution of the differential equation

\[ z \frac{ d^2 f }{ dz^2 } + ( 1 - z ) \frac{ d f }{ dz } + n f = 0 \]

Equivalent to gen_laguerre( n , 0 , z ).
