Test data is in Matlab .mat format and generated here but is stored in the ``euphonic_sqw_models`` repository.
In case the code changes so as to invalidate the test data, you can generate it using runtests('test/EuphonicGenerateTestData.m') here. Then copy the *.mat files in test/expected_output to the euphonic_sqw_models repository and commit it.
Since we include euphonic_sqw_models as a submodule here, it will then include the test data which must be the same in both repository.
The minimum require version of Euphonic is stored in the min_requirements.txt file of euphonic_sqw_models (not here). Like the test data, this is inherited by this repo as a submodule and propagated further.
