MATLAB: How to know which input will switch block pass programmatically

simulinkswitch

Hi,

I'm analysing simulink modell. I have a problem to know which input (1st or 3rd) will switch block pass. With the criteria and second input value can man easily manually know which input will pass. But how can I know it by code?

Thanks

Xiangming

Try reading the second input port value to decide whether the condition is met: https://www.mathworks.com/matlabcentral/answers/96280-is-it-possible-to-read-the-value-of-a-simulink-signal-passing-through-a-signal-line-from-the-matlab

I think the best way of doing this is using an embedded matlab function box.

MATLAB: Adding Toggle Switch programmatically

Hi Osama, If I understand you correctly you could use the following code as an example:

add_block('simulink/Sources/Constant', [gcs, '/Constant1'], 'Position', [0,  0, 30, 30]);
add_block('simulink/Sources/Constant', [gcs, '/Constant2'], 'Position', [0, 45, 30, 75]);
add_block('simulink/Signal Routing/Manual Switch', [gcs, '/Manual Switch'], 'Position', [100, 7,   130, 43]);
add_line(gcs, 'Constant1/1', 'Manual Switch/1');
add_line(gcs, 'Constant2/1', 'Manual Switch/2');

This will result in:
