Rapid Stateflow.Transition finding

Is there a rapid way to find all the 'Stateflow.Transition' from a state A, to a state B?

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))

why don't you use the 'strcmp(s1,s2)'? is the 'isempty(strfind(s1,s2))' more rapid? moreover, it could happen that you may find the transitions from 'upshifting' to 'steady_state', but also the transitions from 'upshifting_whatever' to 'steady_state_whatever'.
