In my workspace im having both constants and mpt.parameters,when im reading from workspace,i can jus access the names but not other fields of mpt.parameter

All_Data=whos
for i=1:length(All_Data)
    All{i,2}=All_Data(i).class;
    All{i,1}=All_Data(i).name;
    if(strcmp(All{i,2},'mpt.Parameter'))
       All_DataType=All_Data(i).DataType;
       %All_value=evalin('base',All{i,1});
       All_value=All_Data(i).Value
       All{i,2}=strcat(All_DataType,'(',num2str(All_value),')');
    else
        All_value=evalin('base',All{i,1});
        All{i,2}=strcat(All{i,2},'(',num2str(All_value),')');
    end
end
