r8col_test, a C code which calls r8col() to demonstrates utility routines for "R8COL" objects, that is, double precision real MxN arrays, considered as N column vectors, each of length M. That is, the data may be thought of as essentially multiple columns, and many operations will be carried out columnwise.
