事先计算图像的标准差，可以用来评判图像变换是否可信(Calculate the standard deviation of the prior image can be used to judge the credibility of image transformation)

The computing world has undergone a revolution since the publication of The C Programming Language in 1978. Big computers are much bigger, and personal computers have capabilities that rival mainframes of a decade ago. During this time, C has changed too, although only modestly, and it has spread far beyond its origins as the language of the UNIX operating system.

模态叠加法计算结构响应，function函数程序(Mode superposition method to calculate the structural response, function function program)

将SVPWM算法应用于三相逆变器中，可以直接使用(SVPWM block used in three-phase inverter)

说明：  从最基本的问题入手，循序渐进，逐渐过渡到较为复杂的数学问题、信号分析问题、力学问题和电 学问题的求解，将MATLAB的学习贯穿在解决不同领域实际问题的过程当中(Starting from the fundamental issue, step by step, gradually transition to more complex mathematical problems, signal issues, mechanical issues and electrical problem solving, learning through the MATLAB to solve practical problems in different areas of the process of)

simulik 仿真基础，讲解matlab/simulink中各种模块的应用(the basis of the simulink simulation)

经典的信息论准则估计信号源个数。 使用空间谱估计理论，模拟发射信号由天线阵列接受采样。经过AIC和MDL两种算法，估计出采样序列中信号的个数，所加噪声是白噪声。(Classical information theory for sources number estimation. It s spatial spectrum estimation theory. it analogs transmission signal from the antenna array . It uses two algorithms“ AIC and MDL ”to estimate the number of sampled signal sequence. the added noise is white noise.)

介绍差分运算的工作原理以及每条线的对应连接等使用方法(Use Works introduce differential operation of each line and the corresponding connections)

说明：  交互多模型算法，用于目标跟踪等，是目前比较理想的算法之一(Interacting multiple model algorithm)

数学实验中的最速落径问题 A,B是不在一条铅垂线上的两点，在链接A,B两点的所有光滑曲线中，找出一条曲线，使得初速度为零的质点，在重力的作用下，自A点下滑到B点所需的时间最短 (Mathematical experiment steepest drop Path problems A, B is not a vertical line of two points, the link A, B two points in all the smooth curve, to find a curve, the initial velocity of the particle is zero, gravity role, and since the point A to B points decline in the time required for the shortest)
