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, (c) 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?

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');
opportpos = get(PH.Outport,'Position');
%add from and goto blocks
gotoblockhandle = add_block('simulink/Signal Routing/From',[Modelname '/goto']);
fromblockhandle = add_block('simulink/Signal Routing/Goto',[Modelname '/from']);
%set position near to subsystem you can change 70 100 and 7 on how far you
%want to keep and size of block
set_param(fromblockhandle,'Position',[opportpos(1)+70 opportpos(2)-7 opportpos(1)+100 opportpos(2)+7 ]);
set_param(gotoblockhandle,'Position',[ipportpos(1)-100 ipportpos(2)-7 ipportpos(1)-70 ipportpos(2)+7 ]);
