    %% Linearize Model at Simulation Snapshot Time
%%
% Open the Simulink model.
sys = 'watertank';
open_system(sys)

%%
% To compute the closed-loop transfer function, first specify the
% linearization input and output signals.
io(1) = linio('watertank/PID Controller',1,'input');
io(2) = linio('watertank/Water-Tank System',1,'output');

%%
% Simulate |sys| for |10| seconds and linearize the model.
linsys = linearize(sys,io,10);
