c_mean

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

ZFFT轨道信号上应用的一些文档，这些文档是从诸多文档中挑选出来的，很有参考价值。分两次上传。这是第二次上传。其中一次包括ZFFT的MATLAB实现。(The application of the track signal ZFFT some documents, these documents are from a number of selected documents, a good reference. From two. This is the second upload. One MATLAB, including the realization of the ZFFT.)

随机过程中利用生灭过程对于不同的排队方式进行效率讨论(Random process using a birth-death process for different queue mode efficiency discussion)

Formant_tracker based on LPC Analysis format:[formants]=formant_tracker(input,dimension,step,window_size,p,threshold)

MATLAB中数值分析如拉格朗日插值、牛顿法求解方程组、LU分解等(MATLAB numerical analysis such as Lagrange interpolation, Newton' s method for solving equations, LU decomposition, etc.)

在AWGN信道下的LDPC码的二进制BP算法译码(AWGN channel in the LDPC decoding algorithm for binary BP)

基于matlab 的 dft 的 fft 的 是吸纳(the same as before fft dft )

含有完整的指纹处理步骤，是用MATLAB进行编程的。主要有基于纹理的指纹特征的提取和分析。(Contains a complete fingerprint processing step is carried out using MATLAB programming. Mainly based on the texture of the fingerprint feature extraction and analysis.)

一个m函数，可以读取GprMax2d的模型数据，是一个探底雷达正演模拟很有用的m代码(The m function model can the read GprMax2d the data, a dip radar forward simulation is useful m code)

会使用DEBUG软件； 利用DEBUG单步执行功能测试指令的执行 (Will use the DEBUG software the use of functional tests DEBUG single-step instructions to be executed)
