To download the integrator: git clone --recursive git://github.com/knedlsepp/knedlLLG.git
The script "setup_knedlLLG.m" will compile the C++ code.
Standard problem 3 and 4 can be started by running the scripts
examples/standard_problem_3/standard_problem_3.m
examples/standard_problem_3/standard_problem_3_inhomogen.m
examples/standard_problem_4/standard_problem_4_s_state.m
examples/standard_problem_4/standard_problem_4_1.m
examples/standard_problem_4/standard_problem_4_2.m
You will have to start the s_state script before you can start the actual computation.
