I use tensors for representing discrete probability distributions of a few
variables from which I need to compute marginal probabilities, so from my
point of view this things would be quite useful in GSL. Another
application might be boolean/discrete functions.
There seem to be nice packages available in other languages, but none of
them seem to be as easy to use in C as say gsl_matrix. => I might
try to extend gsl_matrix to more dimensions.
