How to set the nearest position of the block from the Simulink from Matlab script?
Hi!
I am working on automated Simulink models transformations (creating models from Matlab Scipt) and I need to:
(a) add a block to simulink from the Matlab script — DONE,
(b) connect it to desired port — DONE,
© put this block close to the connected port — NEED HELP.
I have found that the set_param function is able to change the position, but I have to know the exact coordinations:
set_param([‘sampleModel’ ‘/’ ‘From’],’Position’,[0 50 0 50])
I need to set the nearest possible location of the block to its connected port. It is something like:
set_param([‘sampleModel’ ‘/’ ‘From’],’Position’,’Nearest’). There is any option in ‘Position’ that there is no need to put exact coordinations but only “Nearest”?
How can I achieve that?

For doing this you need to extract position of ports (both inport and outport) of each subsystem then.
you can do like below
Modelname = 'dummy';
new_system(Modelname);
open_system(Modelname);
add_block('built-in/Subsystem',[Modelname '/Subsystem'],'Position',[200 200 300 500]);
add_block('simulink/Sinks/Out1',[Modelname '/Subsystem/out1']);
add_block('simulink/Sources/In1',[Modelname '/Subsystem/in1']);%% from here your point C begins
%get porthandles
PH = get_param([Modelname '/Subsystem'],'PortHandles');
%get position of inport and outport ports of subsystem
ipportpos = get(PH.Inport,'Position');
