在matlab编译环境下对用户界面的编译快速入门教程，对于matlab初学者比较有帮助。(In the matlab compiler environment of the user interface compiler Quick Start Guide, more helpful for matlab beginners.)

说明：  本程序用于完成BPSK、QPSK、pi/4QPSK、OQPSK、8PSK、16QAM、32QAM、64QAM和128QAM的调制仿真。并可任意扩展到MPSK和MQAM。程序分成四个部分，fir.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； modal.m 为主程序，完成岁各种信号的基带星座图映射、脉冲成型和调制；pi4QPSK.m 为pi/4QPSK信号的星座图映射程序；test1.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, pi/4QPSK, OQPSK, 8PSK, 16QAM, 32QAM, 64QAM and the modulation 128QAM simulation. Arbitrary and may be extended to MPSK and MQAM. Procedures are divided into four parts, fir.m of baseband symbol pulse sequences forming, optional rectangular pulse, raised cosine square root raised cosine pulse and pulse modal.m-based procedures, the completion of the age range of the base-band signal constellation diagram mapping, pulse shaping and modulation pi4QPSK.m for pi/4QPSK signal constellation diagram mapping procedures test1.m given spectrum shows a simple test.)

function [a,b,err] = shanks(x,p,q) SHANKS Model a signal using Shanks method ---- Usage: [a,b,err] = shanks(x,p,q) The sequence x is modeled as the unit sample response of a filter having a system function of the form H(z) = B(z)/A(z) The polynomials B(z) and A(z) are formed from the vectors b=[b(0), b(1), ... b(q)] a=[1 , a(1), ... a(p)] The input q defines the number of zeros in the model and p defines the number of poles. The modeling error is returned in err.

驱动力和制动力是车辆纵向力学特性中重要部分，本程序采用matlab，根据发动机的万有特性曲线和循环工况，绘制出车辆的驱动力和制动力随时间的关系(The driving force and braking force is an important part of the vehicle longitudinal mechanical properties, the program uses matlab, according to the universal characteristic curve of the engine and the driving cycle, to map out the driving force and braking force of the vehicle over time)

基于matlab/simmechanics舵机 输出铰链机构的仿真(Based on matlab/simmechanics output steering gear hinge body simulation)

利用matlab 制作GUI系统 模拟并分析LTE 基站的功效与多种调制方式之间的配合 从而得出最优化方案。 (Produced using matlab GUI system simulation and analysis of the effectiveness of LTE base station with a variety of co-ordination between the modulation and thus finding the most optimal solution. discription: 1.At the beginning ,the Base Station covers 20 UEs ,each uses 5 RBs 2.the new UE inserts to the system would also use 5RB 3.the total resource for the system : 100 RBs)
