I have a simulink model, I need the block handles of the output ports of a subsystem, but when I use get_param it returns different handles. Is there a way to get the block handles from this function, the ones that are returned by gcbh?

blckPortHandles = get_param(sys, 'PortHandles');

Block handles can be obtained by using the parameter 'PortConnectivity'.

blckHandles = get_param(gcbh,'PortConnectivity') returns structures containing source and destination handles of all blocks.

blckHandles = get_param(gcbh,'Handle') also returns the handle of each block.

I hope this helps.

Thanks, but, unfortunately, it is not what i was looking for. The functions you suggest return the same thing , i think it is called port handle, and what i need is block handle, which is returned when you call gcbh, when the port is selected.

在 MATLAB Online 中打开

Port handles are the handles of the ports(the small > at the border of the subsystem). These are NOT the outports' block handles.

To get the outport handles, first find the outports within the subsystem (using find_system) second use, get_param(blockName, 'Handle')

example:

allOutports = find_system(sys, 'BlockType', 'Outport');
allOutportsHandles = get_param(allOutports, 'Handle');

Hey ES, I used ur logic inorder to get the Outports' block handles, but when I'm doing find_system, I'm just getting 0x1 cell, but I actually have 9 ports connected
