Database of parameters using in Petri Toolbox 

A -	adjacency matrix
B - 	matrix of IB states (invariant behaviour - instantaneous firing speeds remain constant during delta period)
	j-th column of B corresponds to j-th IB state (representing the marking at the begining of delta period)
C - 	incidence matrix
D -	row vector of delta periods (j-th entry of D corresponds to the j-th IB state)
RM - 	matrix of all reachable markings
M0 - 	initial marking of net
M -	marking of the STPN on the end of simulation
P - 	matrix of P-invariants 
Pre -	matrix od pre-conditions
PrioT - 	priority of transition; 0 indicates no priority (or lowest priority)
Post - 	matrix of post-conditions
Seq - 	the two row matrix of firing sequence (1st row - tick, 2nd row - transition fired)
ticks -	integer number of simulation ticks
TimeT -	column vector of time, associated to the transitions
TypeT -	column vector of transitions types :
                    0  -  Zero timed transition
                    1  -  Timed transition
                    2  -  Stochastic time transition with unifom distribution
V - 	column vector of maximal firing speeds associated to the transitions
VV -	j-th column of matrix VV corresponds to instantaneous firing speeds during j-th IB state
XX -	matrix of information needful for construction a graph of reachable markings
