Computational Methods in Science and Technology
Preserved Fulltext
The paper presents the algorithm and description of the meigval procedure written in FORTRAN 90 language which was designed for calculation of the maximum eigenvalue of transfer matrix for one-dimensional S = 1/2 Heisenberg model. The procedure is available at the Poznań Supercomputing and Networking Centre on a Cray J916 supercomputer in the numerical procedure library /lib/mestat.a.
