In this work, a discrete structure representation of SN P systems with extended rules and without delay is proposed. Specifically, matrices are used to represent SN P systems. In order to represent the computations of SN P systems by matrices, configuration vectors are defined to monitor the number of spikes in each neuron at any given configuration; transition net gain vectors are also introduced to quantify the total amount of spikes consumed and produced after the chosen rules are applied. Nondeterminism of the systems is assured by a set of spiking transition vectors that could be used at any given time during the computation. With such matrix representation, it is quite convenient to determine the next configuration from a given configuration, since it involves only multiplication and addition of matrices after deciding the spiking transition vector. }, isbn = {978-84-9887-518-8}, issn = {0302-9743}, doi = {10.1007/978-3-642-18123-8_29}, url = {http://link.springer.com/chapter/10.1007/978-3-642-18123-8_29}, author = {XiangXiang Zeng and Henry Adorna and Miguel A.
