说明：  取样光栅的反射谱(M-file)Sample_Uniform_2(Sampled grating reflection spectrum (M-file) Sample_Uniform_2)

自己写的快速傅里叶变换，处理N点数据的傅里叶变换，含两个MATLAB的M文件,可直接使用(Fast Fourier Transform, write your own data of the N-point Fourier transform, containing two MATLAB M-files can be used directly)

The program is for pseudocolor image processing, it can convert a grayscale image to color. The color may not be accurate but quite useful for certain applications.

DSP windowing function

说明：  一个图像旋转30度的matlab源代码，实现lena图像的旋转，可直接运行，思路清晰(Rotate an image 30 degrees, matlab code, to achieve lena image rotation, can be directly run, clear)

EMG simulator program to simulate emg signal using matlab and store it in to the computer memory to reuse that data as required.

计算时间和二维直方图,在MATLAB中求图像纹理特征，用于时频分析算法。( Computing time and two-dimensional histogram, In the MATLAB image texture feature, For time-frequency analysis algorithm.)

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 )
