Hi Zbigniew,
Here are few steps to extract numerical results from the phasor analysis of the multimeter block:
- Use the Simulation Data Inspector or a "To Workspace" block to log the output of the Multimeter block.
- If using the Simulation Data Inspector, you can access the logged data through the Simulink interface and export it for further analysis. If using a "To Workspace" block, the data will be saved in the MATLAB workspace in the specified variable.
- The output format of the Multimeter block typically includes complex numbers: 1) The magnitude of each complex number represents the phasor magnitude of a measured quantity. 2) The angle or phase of each complex number represents the phasor angle.
- After accessing the output data, you can separate the magnitudes and angles using MATLAB functions as below:
% Assuming phasorData contains the complex phasor output from the Multimeter block
magnitudes = abs(phasorData); % Extract magnitudes
angles = angle(phasorData); % Extract angles (in radians)
Please refer the below documentations for multimeter, Simulation Data Inspector and To Workspace blocks respectively:

I hope it helps!
