Simulink custom context menu item minimal example

In the directory you have opened in MATLAB, create sl_customization.m:

sl_customization.m

function sl_customization(cm)
  cm.addCustomMenuFcn('Simulink:ContextMenu', @getMyMenuItems);
end

function schemaFcns = getMyMenuItems(callbackInfo)
  schemaFcns = {@getItem1};
end

function schema = getItem1(callbackInfo)
  schema = sl_action_schema;
  schema.label = 'Custom item';
  schema.userdata = 'Custom item';
  schema.callback = @myCallback1;
end

function myCallback1(callbackInfo)
  disp(['Callback for item ' callbackInfo.userdata ' was called']);
end

function sl_customization(cm)
  cm.addCustomMenuFcn('Simulink:ContextMenu', @getMyMenuItems);
end

function schemaFcns = getMyMenuItems(callbackInfo)
  schemaFcns = {@getItem1};
end

function schema = getItem1(callbackInfo)
  schema = sl_action_schema;
  schema.label = 'Custom item';
  schema.userdata = 'Custom item';
  schema.callback = @myCallback1;
end

function myCallback1(callbackInfo)
  disp(['Callback for item ' callbackInfo.userdata ' was called']);
end

Now you need to run

in MATLAB once.

In Simulink, this will add Custom item to the right-click context menu:
