i need matlab code of ieee nine bus system for fault dianosis

i need matlab code of ieee nine bus system for fault diagnosis in state space model.i have state space model of generator.i want to apply it on ieee 9 bus system in matlab coding not simulink

Note: ieee 9 bus Simulink model is available at https://www.mathworks.com/matlabcentral/fileexchange/45936-ieee-9-bus and see also https://www.mathworks.com/matlabcentral/fileexchange/65385-wscc-9-bus-test-system-ieee-benchmark and https://www.mathworks.com/matlabcentral/fileexchange/66018-ieee-9-bus-transient-stability-analysis?s_tid=FX_rc2_behav and also https://www.researchgate.net/post/Does_any_one_have_an_IEEE_nine_bus_system_simulink_model .

However these are all either Simulink or Simscape Electronics.
