PCA(主成分分析法)、LDA(线性判别法)两种方法是主要的的线性降维法，有非常好的效果，希望对大家能够有用！ 已通过测试。 (PCA (Principal Component Analysis), LDA (linear discriminant method) two methods are the main linear dimensionality reduction method, with very good results, we hope to be useful! Has been tested.)

这是关于matcom和C++联合编程的资料，可以实现脱离matlab环境来进行编程(This is joint programming on matcom and C++, the data can be achieved out of the matlab environment for programming)

利用matlab的gui设计的带有输入和输出功能的界面图形，实现等距线可视性很强，自己独立编写的数据和图形，学习非常值得,实现 ga pca bp和svm压缩图像，matlab语言(Using GUI of MATLAB to design interface graphics with input and output functions, realizing the visibility of isometric line is very strong, and it is very worthwhile to study the data and graphics independently written by oneself, realizing GA PCA BP and SVM compressed image, MATLAB language)

解决储罐内的二维扩散对流问题，可用在多孔介质中的运算，能够很好的解决问题(Solve the problem of one dimensional convection diffusion)

演化计算是基于随即搜索的新算法；它的技术模型源于自然的演化。下面是一个例子，该函数是典型的多峰（震动剧烈）的函数。用的算法是郭涛算法。(Evolutionary Computation is based on the then new search algorithm its technical model derived from natural evolution. Here)
