主成分分析是把原来多个变量划为少数几个综合指标的一种统计分析方法。 从数学角度来看，这是一种降维处理技术。(Principal component analysis (PCA) is a statistical analysis method that divides a number of variables into a few comprehensive indexes.From a mathematical point of view, this is a kind of dimensionality reduction technology.)

说明：  Matlab的数理统计工具箱是Matlab工具箱中较为简单的一个，其牵扯的数学知识是大家都很熟悉的数理统计(Matlab statistics toolbox of Matlab toolbox is a relatively simple, the mathematics involved is that we are familiar with the knowledge of mathematical statistics)

维数约简工具箱源代码，包括PCA、LLE等学习算法，可用于模式识别、数据挖掘和统计分析等。(dimension reduction toolkit source code, including the PCA, LLE and other learning algorithms can be used for pattern recognition, data mining and statistical analysis.)

蒙特卡罗模拟光散射程序，粒子随机分布，绝对可以直接运运行。带有简单说明～～～～～～！， (Monte Carlo simulation of light scattering process, the particles are randomly distributed, can definitely be shipped directly to run. With a brief description ~ ~ ~ ~ ~ ~! ,)

完成一个利用矩形信号星座图的M=16的QAM通信系统的Monte Carlo仿真(the matlab source code of QAM)

本书详细介绍了matlabsimulink工具的基本用法和应用 (The book details the basic usage matlabsimulink tools and applications)

具体实现三维图像的仿射变换，比较适用于matlab的初学者的。(Concrete realization of three-dimensional image of the affine transformation to compare the application of the beginners in matlab.)

说明：  对于给定的滤波器参数，利用脉冲响应不变性法设计数字低通滤波器，并绘出了设计后的数字滤波器的特性曲线。(This code uses impulse invariant method to design a digital low-pass filter under given filter parameters,then it plots the designed filter s characteristic curve.)
