How to access parameter attributes from data dictionary in Simulink block
显示 更早的评论
Hello,
I am using a data dictionary for my model in Simulink to access parameters. I have defined the parmeter values and its other attributes such as min value and max value etc.
I want to call the min and max values in a simulink block e.g., as constant. I tried to call it as
Param.Min
and
Param.Max
It shows the value but gives me error while running the model saying "dot value attribution is not supported."
Does anyone know how to access these attributes without redefining them? I am using following code to create my data dictionary.
myDictionaryObj = Simulink.data.dictionary.create('myDictionary.sldd');
myDictionaryObj = Simulink.data.dictionary.open('myDictionary2.sldd');
toolDataSectObj=getSection(myDictionaryObj,'Design Data');
ParameterFile = readtable('test_Param.xlsx');
for i = 1:height(ParameterFile)
param = Simulink.Parameter;
param.Value = ParameterFile.Value(i);
param.Max = ParameterFile.Max(i);
param.Min = ParameterFile.Min(i);
param.Description = char(ParameterFile.Desc(i));
param.Unit = char(ParameterFile.Unit(i));
addEntry(toolDataSectObj, char(ParameterFile.Parameter(i)), param);
end

By default, Param.Min refers 'Param' as a structure and 'Min' as one of its field.
I've tested it. You can use
Simulink.data.evalinGlobal(bdroot,'Param.Min')
If 'Param' is in base workspace, it would be evalin('base','Param.Min')

Need to add two single-quote symbols. 'Param.Min'
