Coefficients of Jacobi-Eisenstein series of index 1

[Emmanuel ROYER <emmanuel.royer@uca.fr>]

Hello!

With Pari-gp (what else;)), is there a way to compute the coefficients
of the Jacobi-Eisenstein series of a given weight and index 1 (for
example with Cohen's function: see Eichler & Zagier, The theory of
Jacobi forms, pages 22).

Thanks!
Emmanuel
