  QCDLAB is a set of programs, written in GNU Octave, for lattice QCD
computations. Version 2.0 includes the generation of configurations for the
SU(3) theory, computation of rectangle Wilson loops as well as the low lying
meson spectrum with Wilson fermions. Version 2.1 includes also the computation
of the low lying meson spectrum using minimally doubled chiral fermions. In
this paper, we give a brief tutorial on lattice QCD computations using QCDLAB.
