get_fsm_state.m

CheckMate is a MATLAB-based tool for modeling, simulating and investigating properties of hybrid dyn

function [state_name,state_number] = get_fsm_state(block_name,q)

% Get the FSM state for the specified FSMB given the composite FSM state
% vector.
%
% Syntax:
%   "[state_name,state_number] = get_fsm_state(block_name,q)"
%
% Description:
%   Given the composite FSM state vector "q", find the active state name and
%   the state number for the FSMB specified by "block_name". The state
%   name is returned in the string "state_name" and the state number is
%   returned in the integer "state_number".
