How do I check if a subsystem handle is for a stateflow chart

Hello,
I am trying to write a script that parses my model identifying all subsystems for subsequent processing/modifications via the script.
However, when I have a handle that actually corresponds to a stateflow chart I need to switch to using the stateflow API but how can I easily check if a subsystem handle is a stateflow chart?

use the parameter : SFBlockType
flgChart = strcmp(get_param(gcs,'SFBlockType'),'Chart');

hi
You can do it by utilizing ErrorFcn callback parameter,for chart its value is 'Stateflow.Translate.translate', may be we can use it to differentiate Stateflow chart.
The better ways to do the same is to find the object of the block
obj=get_param(gcbh,'Object')
then checking it for chart using following command :
tmp_Check= obj.find('-isa','StateFlow.Chart');
if(~isempty(tmp_check))
{
%% Stateflow Chart;
else
%% Simulink object
}

function result = is_subsystem_stateflow(handle_subsystem)
if strcmp(get_param(handle_subsystem, 'BlockType'), 'SubSystem')
obj = get_param(handle_subsystem,'Object');
stateflow = find(obj, '-isa','Stateflow.Chart');
subsystem_path = [get_param(handle_subsystem, 'Parent'), '/', get_param(handle_subsystem, 'Name')];
if (length(stateflow) == 1) && strcmp(stateflow.Path, subsystem_path)
result = true;
else
result = false;
end
else
result = false;
end
end

Use the "MaskType" property of the subsystem... it is equal to 'Stateflow' for a Stateflow chart.

Hello Guy,
I am currently using MATLAB 2014a and recently came to my observation that 'MaskType' property of state-flow block is empty.(Till 2011a it was same what you mentioned in above answer) Is there a new function introduce to differentiate between a normal subsystem and a State flow chart? Can you kindly share the details. Thanks in advance.

Hi,
I have the same problem: MaskType is empty since R2012b. Is there a Simulink API (get_param) solution available?
Thanks.
