I am trying to create a function that can create a block table that contain their Handle, FullName, BlockType, Parent by using struct. However each time I get enter a model name, it said
Error in createBlockTable (line 9)
tableStruct = struct(get(gcb), 'Handle', get(i), 'FullName');
Here is my code
function blockTable = createBlockTable(modelName)
load_system(modelName);
getBlock = find_system(modelName, 'FindAll', 'on', 'FollowLinks', 'on', 'LookUnderMasks', 'all', 'Type', 'Block');
blockCell = cell(1,length(getBlock));
for n = 1:length(getBlock)
for i = getBlock(n, 1)
tableStruct = struct(get(i), 'Name');
end
end
blockTable = assign(tableStruct, blockCell);
end
I am thinking that I mess up at line i = getBlock(:,1), but I do not know how to solve this problem. Thanks

Is i a vector? What does it show if you simply do this
i = getBlock(:,1)
whos i
Maybe if i is a single number you want to do this:
for n = 1:length(getBlock)
gb = getBlock(n, 1)
tableStruct = struct(get(gb), 'Name');
end
but I don't have Simulink so that's just a wild guess.

No need to use for-loop. cell2struct() can do the job as in my example.

This inner loop does not make sense.
for i = getBlock(n, 1)
tableStruct = struct(get(i), 'Name');
end
Each block has different properties so don't expect you can use get() to create a universally consistent structure array. get() already returens a structure. It contains different field names for each block.
The proper way is to go through a loop, get the value for "Handle, FullName, BlockType, Parent" and then construct the structure or table.
You could also do get(getBlock,'Handle') or get(getBlock,'Name') to get the property values for all the blocks at once, but to do get(getBlock,'BlockType') or get(getBlock,'Parent'), you need to exclude the model itself.

blockStruct=cell2struct([Names,Parents],{'Names','Parents'},2)
