On the one hand, we prove that an efficient computation for these P systems can be described using linear algebra techniques. In particular, we show that the computation for getting a configuration in such P systems can be carried out by multiplying appropriate matrices. On the other hand, we also show that membrane computing techniques can be used to get the nth power of a given matrix.</style></abstract><custom1><style face="normal" font="default" size="100%">0.838</style></custom1><custom2><style face="normal" font="default" size="100%">59/92 - Q3</style></custom2></record></records></xml>
