Hello, my problem is about creating Simulink Model in with script, due to variable model size I want to generate my model with help of for loops. When I use such command:

    for k=1:n
    Submodulename =sprintf('Submodule_%d' ,k);  
    pos = [x y+3*k*offset (x+w) (y+h+6*k*offset)];
    add_block('NPC_MMC_Library/Submodule', Submodulename,...
        'Position',pos);
    end

Even my variable block name Submodulename is changing but add_block doesn't work,

thanx for any help in advance, Regards

I see you have defined a source block ('NPC_MMC_Library/Submodule'), however your destination doesn't appear to include the model name you are adding it to. I would expect your source to be of the format ['my_model/', Submodulename].

The reason it is failing is you are trying to add a block without stating which model you are adding it to.

Try this:

    for k=1:n
    Submodulename =sprintf('Submodule_%d' ,k);  
    pos = [x y+3*k*offset (x+w) (y+h+6*k*offset)];
    add_block('NPC_MMC_Library/Submodule', ['my_model/', Submodulename], ...
        'Position',pos);
    end
