RWSYST — A filing system for coefficients and eigenvectors

Title of program: RWSYST Catalogue Id: AAFC_v1_0 Nature of problem In most nuclear physics calculations sets of real numbers are used (e. g. eigenvectors, coefficient vectors) which are characterized by a set of quantum numbers. For the fast retrieval of the vectors, the quantum numbers can usually be encoded to an index and the vectors stored in direct access files. This method, however, is costly in disc space, since the vectors have variable length. A solution is needed which will combine the fast retrieval characteristic of direct access with the economy of ...
