how to convert structure variables into a simulink.parameter object

Iam storing varaibles in targetStruct from excel sheet. For example targetStruct has variables B00200, B1115 under name field.

I want to convert those structure variables(B00200, B1115) into a simulink.parameter object in the targetStruct . is tis possible?

The below is the code .

T = readtable('VCU_UDS_DTC_Information_00_06_Backup.xlsx','Sheet','VCU_0.6');

dataStruct=table2struct(T);

targetStruct = struct([]);

for i=1:numel(dataStruct)

b=dataStruct(i).SAE_J2012_DTC;

c=dataStruct(i).SAE_J2012_FTB;

b=num2str(b);

c=num2str(c);

concat=strcat(b,c);

targetStruct(i).name=concat;

To convert the variables stored in the 'targetStruct' structure into a 'Simulink.Parameter' object, you can modify your code as follows:

T = readtable('VCU_UDS_DTC_Information_00_06_Backup.xlsx','Sheet','VCU_0.6');
dataStruct = table2struct(T);

targetStruct = struct([]);
for i = 1:numel(dataStruct)
    b = num2str(dataStruct(i).SAE_J2012_DTC);
    c = num2str(dataStruct(i).SAE_J2012_FTB);
    concat = strcat(b, c);
    targetStruct(i).name = concat;

    % Create Simulink.Parameter object
    paramObj = Simulink.Parameter;
    paramObj.Value = targetStruct(i).name;
    targetStruct(i).paramObj = paramObj;
end

In this code, after concatenating the variables 'b' and 'c', a 'Simulink.Paramete'r object 'paramObj' is created and assigned the concatenated value. Then, the 'paramObj' is added as a field 'paramObj' to the 'targetStruct' structure.

Please note that the functionality of converting 'string' to 'Simulink.Parameter' object as been introduced in MATLAB R2023b. I have verified the above code in the aforementioned release and it might produce some error in the previous releases. If you are using a previous release, I would suggest you to upgade to MATLAB R2023b to convert 'string' values to 'Simulink.Parameter'. Here is the MATLAB Socumentation for the same:
