You can do that using a simple MATLAB script using the Stateflow API. Find the Stateflow API below: http://www.mathworks.com/help/stateflow/programmatic-manipulation.html
Here is a simple example that looks for transitions between the states "upshifting" and "steady_state". To run the example, open the model sf_car and run the following code:
rt = sfroot;
transArray = rt.find('-isa','Stateflow.Transition');
len_transarray = length(transArray);
x = zeros(len_transarray,1);
y = zeros(len_transarray,1);
for i = 1: len_transarray
if ~isempty(strfind(get(get(transArray(i),'Source'),'LabelString'),'upshifting'))
x(i) = i;
end
if ~isempty(strfind(get(get(transArray(i),'Destination'),'LabelString'),'steady_state'))
y(i) = i;
end
end
output = transArray(find(x>0 & y > 0))
