How to get all parameters for a Simulink masked system at once?

I wonder if there is a way to obtain all parameters in a Simulink masked system. For example, assuming a given masked system with parameters "otype" for "Output data type", "omode" for "Output data mode", and many more. The current to see what parameters existing is right-click the subsystem and select "Edit Mask" to see all parameters and their options.

But this is inconvenient for scripting a Simulink System. It would be handy that if I can use get_param command (or some other commands) to pull all parameters and available options.

The same solution may be applied to built-in blocks, not only masked subsystem. I just happen to encounter the subsystem problem.

Just to add that I want more than these two commands:

get_param('model/sub_block', 'DialogParameters')

and

get_param('model/sub_block', 'ObjectParameters')

The returns from these two aren't sufficient for scripting.

According to the documentation, get_param('model/sub_block', 'DialogParameters') should return the "List of names/attributes of block-specific parameters for an unmasked block, or mask parameters for a masked block." - could you please explain why this is not sufficient?

[Steven Huang]

If you try get_param('model/sub_block', 'DialogParameters'), you will see that there is no current value is set to. And if there are options, the options won't show either unless combined with other parameters. In short, scripting is difficult to be automatic.

I'm assuming that you want to do is get the list of dialog parameters and their values? In that case, you need to write something like:

dialogPrms = get_param('model/sub_block', 'DialogParameters');
dialogPrmNames = fieldnames(dialogPrms);
for idx = 1:numel(dialogPrmNames)
   dialogPrmValue = get_param('model/sub_block', dialogPrmNames{idx})
end

how can we get all the blocks and its dialog parameters and their values?

@Malu - try:

get_param(gcb, 'ObjectParameters')
