>>> from pharmpy.modeling import fix_or_unfix_parameters, load_example_model
>>> model = load_example_model("pheno")
>>> model.parameters['PTVCL']
Parameter("PTVCL", 0.00469307, lower=0.0, upper=∞, fix=False)
>>> model = fix_or_unfix_parameters(model, {'PTVCL': True})
>>> model.parameters['PTVCL']
Parameter("PTVCL", 0.00469307, lower=0.0, upper=∞, fix=True)

Returns:: Model – Pharmpy model object
