I want to add an dropdown menu in the app designer.
with each option a stored m-file should be loaded. If possible the name should be there instead of option1/2/3. but I have no approach.
properties (Access = public)
var1=load('1.mat'); % specify the path to mat file missing
the rest unfortunately does not work

You may follow these steps
  1. Open App Designer by typing appdesigner in command window and Select a Blank app
  2. Drag and drop the Drop Down menu from component library to design view
  3. In Component browser, change Items in drop-down section to None, MatFile1, MatFile2, MatFile3
  4. Go to Code view and add a callback by pressing '+' symbol in code browser and change component to Drop-Down
  5. Add this code in the new callback and save the app
value = app.DropDown.Value;
switch value
case 'MatFile1'
f = @(x) load(x, 'VarName1'); % VarName1 is the variable to be loaded from MatFile1
out = f(value);
case 'MatFile2'
f = @(x) load(x, 'VarName2'); % VarName2 is the variable to be loaded from MatFile2
out = f(value);
case 'MatFile3'
f = @(x) load(x, 'VarName3'); % VarName3 is the variable to be loaded from MatFile3
out = f(value);
If the variable name is same for all file, you may remove switch condition
