MATLAB矩阵及其运算 MATLAB矩阵及其运算 MATLAB矩阵及其运算(MATLAB matrix and its operation MATLAB matrix and its operation MATLAB matrix and its operation)

说明：  求mel频率倒谱系数的程序，求的准确，时间相比其他程序多一点(Mel frequency cepstrum seeking the procedure, find the exact time a little more compared to other programs)

该程序用于求解时间延迟t和嵌入维数m，该方法不同于自相关函数法和gp法，可以同时求解出两个量t和m的值，非常方面，在求解lyapunov指数时经常用到该方法(The procedure used to solve the time delay t and the embedding dimension m, the method is different from the self-correlation function gp method can solve the two quantities t and the value of m, the very aspect, often used to solve the lyapunov exponentthe method )

不同信噪比对误码率性能的影响，仅供参考，效果还可以(BER performance of different signal to noise ratio on the impact of reference only, the effect can be)

数字水印图像的攻击测试 包括滤波、剪切、添加噪声、jepg压缩攻击等等(Attack test digital watermarking images, including filtering, cropping, adding noise, jepg compression attack, etc.)

电力系统连锁故障分析中的内点法最优潮流模型(Chain failure analysis of power system optimal power flow model of the interior point method)

Matlab codes of FEM

Simulink中延时模块、乘积模块、常数模块、示波器模块等使用例子，可以直接运行，自己编写的。(delay module, product module, constant modules, oscilloscope module usage example in Simulink, can be directly run, written by myself)

通信仿真中的混沌数字键控Matlab分析程序，包括时域和频域(Chaos digital key analytical procedures)

ZEMAX是美国 Radiant Zemax 公司所发展出的光学设计软件，可做光学组件设计与照明系统的照度分析，也可建立反射，折射，绕射等光学模型，并结合优化，公差等分析功能，是套可以运算sequential及Non-Sequential的软件。(ZEMAX is a wonderful too for designing light .)
