QCDLAB is a package of MATLAB/OCTAVE functions for lattice QCD calculations. Version 1.1 This version extends the functionality of 1.0 version. The most important additions are the multiplication functions with the Wilson-Dirac operator and the Domain Wall Fermion operator. An additional function creates the whole Wilson-Dirac matrix in the sparse format. This allows to use the QCDLAB 1.0 linear algebra capabilities without any change. For more information refer to the QCDLAB documentation.
