归一化后截止频率为0.2的数字低通滤波器，并且能有效滤掉工频干扰，使心电信号有效表达信息。(The normalized digital low-pass filter with a cutoff frequency of 0.2, and can effectively filter out power frequency interference, so that the ECG signal can effectively express information.)

用remez算法实现低通滤波器 并绘制频谱图(Remez algorithm using low-pass filter and draw a spectrum map)

牛頓優化算法，matlab代碼，已經驗證過可運行出正確結果(Newton optimization algorithm, matlab code has been verified to run the correct results)

里面包含m序列，gold序列的生成函数，还有自己编写的自相关函数的M文件。(Which contains m-sequence, the gold generating function of the sequence, as well as I have written the autocorrelation function M-file.)

本程序主要实现图像的骨架化。细化和骨架化操作是把区域的面宽度缩到最小，即单像素宽度，也就是把物体变细，直到现最小的像点连通性。(The main procedures of the skeleton of the image. Refinement and skeleton operation the face width of the region is reduced to a minimum, i.e., a single pixel width, which is the object thinner, until now the smallest image point connectivity.)
