Hi,
I understand that you have a Simulink model and a MAT file which contains few signal and their corresponding value. You want to replace all the "Inport" block of your Simulink model with "Signal Builder" block if the corresponding signal exist in the MAT file.
You can try out the following code which will basically iterate over all the "Inports" block in your Simulink model, Check if the signal exist in the MAT file or not and then it will replace the "Inport" block with the "Signal Builder" block
% Step 1: Load the .mat file containing the signals and their values
matFileName = 'signals.mat';
loadedData = load(matFileName);
% Step 2: Open the Simulink model
modelFileName = 'my_model';
open_system(modelFileName);
% Step 3: Identify the Inport blocks and replace them with Signal Builder blocks
inportBlocks = find_system(modelFileName, 'BlockType', 'Inport');
% Loop through each Inport block and replace it with a Signal Builder block
for i = 1:length(inportBlocks)
inportBlock = inportBlocks{i};
inportName = get_param(inportBlock, 'Name');
% Check if the signal exists in the .mat file
if isfield(loadedData, inportName)
% Get the signal data
signalData = loadedData.(inportName);
% Create a new Signal Builder block
signalBuilderBlock = [inportBlock, '_SignalBuilder'];
add_block('simulink/Sources/Signal Builder', signalBuilderBlock);
% Set the position of the Signal Builder block to match the Inport block
inportPosition = get_param(inportBlock, 'Position');
set_param(signalBuilderBlock, 'Position', inportPosition);
% Remove the Inport block
delete_block(inportBlock);
% Assign the signal data to the Signal Builder block
timeData = signalData.time;
valueData = signalData.data;
signalBuilderData = [timeData, valueData];
signalBuilderBlockHandle = get_param(signalBuilderBlock, 'Handle');
signalbuilder(signalBuilderBlockHandle, 'set', 1, 'Signal 1', signalBuilderData);
end
end
% Step 4: Save the modified model as a new file
newModelFileName = [modelFileName, '_modified'];
save_system(modelFileName, newModelFileName);
% Close the model
close_system(modelFileName);
You can run the following command in your MATLAB command window to open the correponding documentation of that function:
add_block:
>> web(fullfile(docroot, 'simulink/slref/add_block.html'))
signalbuilder:
>> web(fullfile(docroot, 'simulink/slref/signalbuilder_cmd.html'))
Thanks
