调频步进信号的产生matlab方式。希望有用！(generating step frequency signal use matlab!)

说明：  非常好的参考资料，帮助学习时频域分析——s变换(Very good reference material, help to learn time-frequency analysis - S transform)

Lucas_Kanade光流算法产生光流场，用matlab编译(Optical flow algorithm Lucas_Kanade optical flow field generated by the compiler matlab)

通过卷积码的学习，建立了卷积码的两种译码方式的simulink仿真模型！(in this part we can use the simulink to realize the convolutional decoding by harddecision and softdecision.)

基于MATPOWER修改而成的潮流计算软件，可以采用直流潮流法、牛顿拉夫逊法、PQ分解法与高斯－塞代尔法解算IEEE9-300节点的潮流。 (MATPOWER modifications made based on the flow calculation software, DC power flow method can be used Newton Raphson method, PQ decomposition method and the Gauss- Cypriot dayr Act solver IEEE9-300 nodes trend.)

通过N个独立的正弦函数叠加来产生窄带噪声(Narrow Noise Generation from N sine function)

说明：  该程序能够成功地基于EPANET进行压力驱动状态模拟。(this program can perform pressure driven simulation based on EPANET.)

说明：  随机森林是一种有监督学习算法，是以决策树为基学习器的集成学习算法。随机森林非常简单，易于实现，计算开销也很小，但是它在分类和回归上表现出非常惊人的性能，因此，随机森林被誉为“代表集成学习技术水平的方法”。(Random forest is a supervised learning algorithm, which is an integrated learning algorithm based on decision tree. Random forest is very simple, easy to implement, and the cost of calculation is very small, but it shows amazing performance in classification and regression. Therefore, random forest is known as "the method representing the level of integrated learning technology".)

说明：  该程序是盲源分离算法中时域—频域分离算法，该算法应用范围广泛。(The procedure is blind source separation algorithm in time domain- the frequency domain separation algorithm, which a wide range of applications.)

说明：  通过修改输入excel表中铺层及材料属性信息，计算层合板的等效刚度及极限强度(The equivalent stiffness and ultimate strength of the laminates are calculated by modifying the information of the properties of the laminates and materials in the excel table.)
