Research of MATLAB Calculations and Simulation based on GPU

The graphics processing unit(GPU) has become an integral part of today's mainstream computing system,modern GPU is not only a powerful graphics engine,but also a highly parallel programmable processor.Peak arithmetic and memory bandwidth of the GPU often significantly exceeded the corresponding peak and memory bandwidth in its CPU.This paper describes a computational simulation method based on GPU general computing framework for the JACKET accelerating MATLAB,draws simulation results through classic FFT algorithm.analyzes the FFT algorithm in the CPU and GPU running environment Gflops and speedup and comes to the conclusion that under JACKET large scale computing and the GPU-based MATLAB simulation program running has been efficiency greatly improved.
