introdution of matlab part 2 and examples

基于MatLab与DSP的滤波器的快速设计方法(MatLab and DSP-based filter design method of rapid)

the mole for window 32bit

机加工自由曲面，由matlab生成设计曲面和设计刀具轨迹（此例为加工椭球面）(Freeform surface machining, surface generated by the matlab design and design tool path (in this case for the processing of the ellipsoid))

关于锁模激光器基础的仿真程序。初学者可以参考(About the mode-locked laser based simulation program. Beginners can refer to )

MatLab Simulations for Radar Systems Designign Using matlab 的源代码(MatLab Simulations for Radar Systems Designign Using matlab source code)

替代数据生成算法。包括常用的随机相位法(shuffle.m and surrogate.m)，周期随机相位法(cycleshuffle.m)和PPS算法(pps.m and findrho.m).(Surrogate data algorithms, including the usual approaches (shuffle.m and surrogate.m), the cycle shuffle version (cycleshuffle.m) and the PPS algorithm (pps.m and findrho.m). )

说明：   让某一频率以下的信号分量通过，而对该频率以上的信号分量大大抑制的电容、电感与电阻等器件的组合装置。 (low-pass filter )

说明：  通过利用Weichselberger模型而产生瑞利衰落信道(rayleigh)

说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)
