Hi Hongcheng, I am afraid you misunderstood the manual of GSL at this point. Just take a look at the following quoted sentence in the manual and make sure you know what it means:
``compare this to the case of the discrete Fourier transform, where samples are taken at points related to the zeroes of the sine or cosine function.'' In fact, to do a discrete Hankel transform of a particular function f, you just need to provide a sequence of samples of f, which normally are obtained indeed on a uniform manner.
