How do i recover all the entries to a stateflow chart into a structure in matlab workspace through matlab script ?

I have a steflow chart which has inputs and outputs .I want to create a structure which recovers all the inputs and outputs of the particular chart block into the structure .When i then call the structure it should automatically show me the entries and outputs .

For example : Entries.name_ofInput1 = *****

Entries.name_ofInput2 = ****

Similarly for the output .

How do i automatically know all the entries of a particular chart in stateflow in matlab workspace through a script ?

Is there any command which gives me access to all the chart Entries and outputs in workspace ?

Any help would be appreciated
