R8COL
Arrays of Columns


R8COL is a C library which contains 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.
