此文件包含有限元分析与应用书籍pdf和相应的matlab源码(the book and the matlab code for the book---finite element analysis and application)

用于实现求取图像中几个区域的质心，并画在图像中！初学者可以看看！(To find the centres of the objects and show them in the picture!)

说明：  DSP从入门到精通，对于初学者是非常好的教程，希望能帮到大家(From introductory to proficient in DSP ,which is a very good course for beginners. I hope it can help you all.)

语音信号处理中应用于定位测试的小程序，将语音信号加载进去即可获得该信号的来波方向(Voice signal processing applied to the positioning test applet, the voice signal is loaded into the signal to obtain the incoming direction)

高斯混合模型，实测有效，适合各种维度的变量(gmm;gaussian mixture model;Gaussian Mixture Modeling)

说明：  本程序可以进行灰色预测，欢迎下载，。。。。。。。。。。。。。。。。(This program can carry out grey prediction, welcome to download,......................)

说明：  利用粒子滤波进行锂离子电池的循环寿命预测(Cycle life prediction of Li-ion battery by particle filter)

说明：  《信号与系统》课本，郑君里，应启珩，杨为理。 第三版清晰版本, 第二版较清晰版本("Signal and system" textbook, Zheng Junli, should be Qi Heng, Yang Weili Clear version of the third edition, clear version of the second edition)

说明：  随机森林算法与 Bagging 算法类似，均是基于 Bootstrap 方法重采样，产生多个训练集。不同的是，随机森林算法在构建决策树的时候，采用了随机选取分裂属性集的方法 本程序中，将乳腺肿瘤病灶组织的细胞核显微图像的 10 个量化特征作为模型的输入，良性乳腺肿瘤和恶性乳腺肿瘤作为模型的输出。用训练集数据进行随机森林分类器的创建，然后对测试集数据进行仿真测试，最后对测试结果进行分析。(Similar to bagging algorithm, random forest algorithm is based on bootstrap resampling to generate multiple training sets. The difference is that the random forest algorithm uses the method of randomly selecting the split attribute set when constructing the decision tree In this program, 10 quantitative features of nuclear microscopic image of breast tumor tissue are taken as the input of the model, and the benign and malignant breast tumor are taken as the output of the model. The training set data is used to create the random forest classifier, then the test set data is simulated and the test results are analyzed.)

实现对逆变器的三相电流、三相电压、三相IGBT温度、三相的频率等采样，涉及了应用层程序和底层程序(Sampling of three-phase current, three-phase voltage, three-phase IGBT temperature and three-phase frequency of inverters is realized, which involves application layer program and bottom layer program.)
