You can leverage MATLAB's APIs for creating and adding entries to a data dictionary programmatically. The functions and their usages are given in detail in the documentation link - https://www.mathworks.com/help/simulink/ug/store-data-in-dictionary-programmatically.html
Here's an example script I created for demonstration purposes:
names = {'Input1', 'Input2', 'Output1', 'Output2'};
dataTypes = {'double', 'int32', 'single', 'boolean'};
dataTable = table(names', dataTypes', 'VariableNames', {'Names', 'DataTypes'});
% a table to store the data in mentioned format - Names and Data Types
dataDictionaryName = 'MyDataDictionary.sldd';
Simulink.data.dictionary.create(dataDictionaryName);
dictObj = Simulink.data.dictionary.open(dataDictionaryName);
sectionObj = getSection(dictObj, 'Design Data');
for i = 1:height(dataTable) % Loop to iterate over the table and add entries to the design data
entryName = dataTable.Names{i};
entryDataType = dataTable.DataTypes{i};
parameter = Simulink.Parameter;
parameter.DataType = entryDataType;
addEntry(sectionObj, entryName, parameter);
end
saveChanges(dictObj);
On executing the script, a data dictionary gets created as shown:
I hope this answers your question. Thanks!
