Hi, I am creating a GUI which contains DropDowns. They are 10 dropdowns as you can see from the code. And I am using assignin to save each one of them into base workspace. But I would like to club all of them into a 2 char array's or 2 cell array's and send only two variables into the base workspace viz, Roll_nos and Projnames_GUI

Answer 1

Create two cell arrays and assign them in the base workspace:

roll_nos = {
  app.StudentInfoDropDown.Value,
  app.StudentInfoDropDown_2.Value,
  app.StudentInfoDropDown_3.Value,
  app.StudentInfoDropDown_4.Value,
  app.StudentInfoDropDown_5.Value
};

projnames_gui = {
  app.ProjectInfoDropDown.Value,
  app.ProjectInfoDropDown_2.Value,
  app.ProjectInfoDropDown_3.Value,
  app.ProjectInfoDropDown_4.Value,
  app.ProjectInfoDropDown_5.Value
};

assignin('base','Roll_nos',roll_nos)
assignin('base','Projnames_GUI',projnames_gui)
