[Help-gsl] Question about Discrete Hankel Transform

[Hongcheng Ni]

Hi everyone,

I'm a newcomer and have a question about discrete Hankel transform (DHT)
in GSL package.

By reading the manual, I find that gsl_dht only supports a non-uniform
grid system in which sampling is done on the zeros of the Bessel
function (of the first kind) J_0.

Does anyone know how to use it on a uniform grid? (Because changing my
existing code from uniform sampling to non-uniform sampling would cost a
lot of time.) Thanks!
