How can I change a component size in MATLAB system composer by means of APIs (command line or MATLAB code) ?

Hi Aidin,
You can use System Composer native APIs for this to interact with your architecture model in an object-oriented manner:
architectureModel = systemcomposer.loadModel('MyArchitecture');
myComponent = lookup(architectureModel, Path='MyArchitecture/MyComponent')
myComponent.Position = [100 100 100 100]
For more information on components, you can reference the following doc page:

thank you for your reply. I'll nosedive into the docs you just shared. I see a lot of potential in this library, the second point sold it to me.

via script:
scTmpArc=open_system('scTmpArc') %sxTmpArc is the name of your system composer file
set_param('scTmpArc/.../..',position',[100 400 500 500]) %the first paramter is the fullpath to your block
The numbers are the dimensions in pixel [x0 y0 x1 y1] meaning that x1-x0 is the lenght, y1-y0 is the height
if you don't know the fullpath you can search for it by doing:
cmpNames=getfullname(Simulink.findBlocks('scTmpArc')) %this will list every component path in cell arrays
you can then parse the cell array to find the name you need (also via script or by hand)
Note: keep in mind that system composer is just a simulink interface from a scripting point of view. Basically all the simulink commands work for both.
