matlab code for Blackman Window....

网络法找切线。当一个曲线在某个点的切线很难找时可用此法。(Network to find the tangent. When a curve tangent at a point when this method is difficult to find.)

introduction to matlab.

高频地波雷达单基地一阶和二阶海杂波程序，毕业设计做的东西(High-frequency surface wave radar monostatic first-order and second-order sea clutter program)

This function takes a quantized analog signal and calculating the signal to quantization noise ratio (SNR)

PID控制算法：模糊免疫PID控制算法以及仿真(PID control algorithm: fuzzy immune PID control algorithm and simulation)

PCA的步骤： 1 先将数据中心化； 2 求得的协方差矩阵； 3 求出协方差矩阵的特征值与特征向量； 4 将特征值与特征向量进行排序； 5 根据要降维的维数d’,求得要降维的投影方向； 6 求出降维后的数据； (PCA steps: 1 of the first data center 2 covariance matrix obtained 3 obtained covariance matrix eigenvalues and eigenvectors 4 eigenvalues and eigenvectors will be sorted 5 according to the dimension of dimension reduction d ' , seek to reduce the dimension projection direction 6, the data obtained after the dimensionality reduction )

说明：  该代码经本人亲自测试，完全通过运行，提取的特征点数量较多(I personally tested by the code, completely by running a larger number of feature points extracted)

matlab的一本很好的资料，含有大量实例，及程序源码(matlab a good information, contains a lot of examples, and program source code)

this code packet is heplful to your optimization studies. especially signal processing area.
