[Matlab] Simulink Real-time (xpc) & Real-time windows target introduction

Matlab provides two real-time library, and this table show feature, support hardware, and description. More detail can look another tutorial : Tutorial : Matlab Real-time windows target with Advantech PCI-1716 card .

	Simulink real-time (XPC target)	Real-time windows target
Feature	Real-time performance approaching 1 kHz in normal execution mode  Real-time performance approaching 20 kHz in external execution mode (with Simulink Coder)	Real-Time Windows Target includes a real-time engine that runs in Windows kernel mode In normal mode, Real-Time Windows Target synchronizes data between the real-time engine and Simulink. Real-time performance approaching 500 Hz in normal mode.
Support hardware	http://www.mathworks.com/products/simulink-real-time/supported/hardware-drivers.html.	http://www.mathworks.com/hardware-support/real-time-windows-target.html
Description	It needs another board to execute real-time task, and this board has real-time OS (always Dos) or micro-controller.	It needs to install windows real-time kernel that matlab provides a real-time engine for executing Simulink® models on a Microsoft® Windows® PC and blocks that connect to a range of I/O devices
