Change all block names Simulinkin a List

Hi,

i have a model from another company to integrate in our own and we want to translate the model first. I dont speak the language and the translator does not know how to use simulink.

Is there a way to get all the names (Block names, Port lables) in a list form? Basically i would need a list of Blockhandle, Old Name. Then the translator can assign new names to the block handles and i can write them back. I know i can use the find_system to get the handle of a known block, but how to get the handle on any block and how to iterate through all?

I understand that you want to get a list of all the block names and port labels in the Simulink model as well as their handles. It can be achieved using “find_system” and “get_param” function as shown in the following code snippet:

% Open the model
model = 'BlockNames';
open_system(model);

% Get all block handles and names
blocks = find_system(model, 'LookUnderMasks', 'all', 'FollowLinks', 'on');
blockNames = get_param(blocks, 'Name');

You can iterate over the handles and replace the names with the translated names in the following way:

for i=1:size(blocks)
    % get the new block name from the newBlockNames array which contains the translated block names.
    translatedName = newBlockNames{i};

    % update the block name using set_param function
    set_param(blocks{i},'Name',translatedName);
end

The “set_param” function is used to modify parameters of Simulink blocks or models programmatically. Refer to these links for more information:
