Matlab is one of the most widely used mathematical computing environments in technical computing. It has an interactive environment which provides high performance computing (HPC) procedures and easy to use. Parallel computing with Matlab has been an interested area for scientists of parallel computing researches for a number of years. Where there are many attempts to parallel Matlab. In this book, we will present most of the past, present attempts of parallel Matlab such as MatlabMPI, bcMPI, pMatlab, Star-P and PCT. Also, we will expect the future attempts. Finally, This book is for readers which have a basic knowledge in Matlab. I expect after reading this book you will able to solve any problem using Parallel Matlab
