describing each.
prim9
matrix of 500 observations with 9 parameters describing each
observation.

Examples are believed to have been
produced from work on the Prim-9 graphics system at
Stanford Linear Accelerator. Probably related to the data cited in
J. H. Friedman and J. W. Tukey,
IEEE Transactions on Computing,
C-23, 1974, pp. 881--889.
If so, these are particle-scattering experiments, and the
columns of the matrices represent some chosen set of parameters
(energy, momentum, etc.) to describe the nuclear reactions.
