Hi 珊,
The following commands can be used to automate the processing of logging a signal without using the "Multimeter" block:
% open the Simulink model (using the example model "power_compensated" here)
open_system('power_compensated');
% Add a 'To Workspace' block to the Simulink model
toWorkspaceBlock = add_block('simulink/Sinks/To Workspace', 'power_compensated/To Workspace');
% Set the variable name for the signal to be logged and its save format
set_param(toWorkspaceBlock, 'VariableName', 'logged_signal');
set_param(toWorkspaceBlock, 'SaveFormat', 'Array');
% Connect the block with its port number to "To Workspace" block for the
% signal you want to log (Demux port number 1 signal in this case)
add_line('power_compensated', 'Demux/1', 'To Workspace/1');
% Run the simulation and the logged signal will be saved to the workspace
sim('power_compensated');
Refer here for more information on the "power_compensated" example model and “To Workspace” block:
