`prim4' is a matrix of 500 experimental observations, with 4 parameters
describing each.
`prim9' is a similar matrix, but with 9 parameters describing each
observation.
.SH SOURCE
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,

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.
