A P system for matrix-vector multiplication

P system is a new kind of distributed parallel computing model, and many variants of it are proposed to solve the problems such as NP problems, arithmetic operation, image processing. Matrix-vector multiplication plays an important role in the numerical and non-numerical Calculations, such as solving linear equations and polynomials. In this paper, we firstly present a family of P systems to implement matrix-vector multiplication in which the elements are real numbers. An instance is given to illustrate the feasibility and effectiveness of our designed P systems. Our work contributes to make P systems solve more complicated computation effectively, and expands the application of membrane computing. © 2015 American Scientific Publishers.
