串口调试助手，可以调节频率来进行串口调试开发，(Serial debugging assistant can adjust the frequency to debug and develop the serial port.)

梯度下降算法实现单变量线性回归，在matlab中(Gradient descent algorithm for single variable linear regression)

介绍五中点云滤波方法：直通滤波器、体素滤波器、统计滤波器、条件滤波器、半径滤波器。(Five-midpoint cloud filtering methods are introduced: through filter, voxel filter, statistical filter, conditional filter and radius filter.)

说明：  可以在混凝土构件内生成随机纤维，可设定纤维数量、构件形状(Random fibers can be generated in the concrete member, and the number of fibers and the shape of the member can be set)

说明：  一种简单有效的测度熵替代方法——近似熵(approximate entropy)方 法.应用以上方法对Logistic映射复杂度进行了分析.结果表明Lyapunov指数和测度熵的值与复 杂度基本呈线性关系,分维数与复杂度的函数关系尚难确定,且与Lyapunov指数、测度熵之间的关 系也不明确. ( Approximate entropy (ApEn) method is also studied. They are applied to analyze the complexity of Logistic map. The conclusion is that Lyapunov exponent and K-S entropy have approximately linear relation with complexity, while it is difficult to determine the relation between fractal and complexity. )
