Re: A point on a d-dimensional sphere

[James Theiler <jt at lanl dot gov>]

you can use gsl_ran_dir_nd (see section 19.22), but the basic idea
is to generate d gaussian deviates {z_1,...,z_d} and then normalize
them using x_i = z_i/R, where R=sqrt(z_1^2+...z_d^2)

if d<4, there are tricks you can use to speed things up.
