Hi everybody, I have a problem and I have not found a solution until now. I have, for example, two blocks on simulink, a block "From" connected to an block "Goto", but in this case I don't know it but the only things I know is that there is the block "From" in that simulink. How can I find, from matlab, the connection between these two block? There is a command from matlab that return this information? I tried with "get_param" but doesn't work! Thank you

Please, what if I have two [known] Simulink blocks and I want to know if they are both connected, how do I go about identifying if connectivity exists between them?

To get the blocks that are connected to your block block1
b=get_param('your_model/block1','PortConnectivity')

b=get_param('your_model/block1','PortConnectivity');
n=numel(b) % number of blocks connected to block1;
%Check if each block from the n blocks is a source block or a destination block
for k=1:n
s=get(b(k).SrcBlock);
f='Source';
if isempty(s)
s=get(b(k).DstBlock);
f='Destinataion';
end
out{k,1}=f;
out{k,2}=s.BlockType;
out{k,3}=s.Name
end
disp(out) % the first column indicate if a block is a source or a destination, the second indicate the type, and the third is the name.

Can you please check the Finding Model utility on File Exchange, this APP will allow you to create custom dataset for your models, wherein you can get the block conectivity patterns as well.
Best Regards,
Shishir.
