Hi all,
how do I change programmatically this:
I have added a MATLAB Function to a Simulink file and clicked on the MATLAB Function and then run mask_it(gcb) see below
function mask_it(block)
maskObj = Simulink.Mask.get(block);
% If a mask already exists, delete it to ensure a clean slate before creating/reconfiguring
if ~isempty(maskObj)
maskObj.delete;
% Get the mask object again (it should be empty now)
maskObj = Simulink.Mask.get(block);
end
% Create the mask if it doesn't exist or was just deleted
if isempty(maskObj)
maskObj = Simulink.Mask.create(block);
end
% Define column headers for the table
% Note: 'Type' 'edit' applies to the entire column.
% 'Name' here refers to the column header, not the parameter name.
maskObj.addParameter('Type', 'edit', 'Name', 'param1', ...
'Prompt', 'params1', 'Value', '0', ...
'Tunable', 'on', 'Evaluate', 'on');
maskObj.addParameter('Type', 'edit', 'Name', 'param2', ...
'Prompt', 'params2', 'Value', '0', ...
'Tunable', 'on', 'Evaluate', 'on');
end
maskObj.set(???)
Many thanks in advance!

Try if you can play with this further, between "Group" or "Table"
>> maskobj=Simulink.Mask.get(gcb);
>> controls = maskobj.getDialogControls
controls =
1×2 heterogeneous Container (Group, Table) array with properties:
Enabled
Visible
AlignPrompts
DialogControls
Name
Tooltip

Hi Fangjun,
I have played around a lot. The main problem is the the lack of documentation what is possible and what not. Topics as Level2 Matlab function and (its) mask are documented sparsly so I have days of trial and error. I hope a Mathworks expert can state if an existing container "Type" can be changed programmatically or not.
The methods and classes suggest: No, it is not possible. However, the GUI manages it so there are most like a methods of sets of methods that are executed in the background.

I agree. If you really need that capability, maybe contact the Mathworks Tech support for help.
