I need to compute the rate-distortion curves for some discrete-time
continuous-amplitude zero-memory sources (i.e., sequences of i.i.d.
random variables), where "distortion" is always mean-square error.

Anyone out there have code/advice for finding these curves?  I know
about the Arimoto-Blahut algorithm, but I'm lost as to how to
implement it for continuous-alphabet sources.

The application is academic, not commercial.

Thanks!
