spectral analysis of autocorreLATION

分解结构振动模态,识别模态参数，将多自由度振动分解为若干单自由度振动的叠加(structural mode decomposition)

根据计盒维数原理编写了求一维曲线分形维数的matlab程序(According to the box counting dimension principle written for the one-dimensional curve fractal dimension of the matlab program)

说明：  这也是一个对初学者有用的MATLAB源码，希望对你有用！( This is also one to the beginner useful MATLAB sound code, hoped that is useful to you! )

Modelling and Control of a Three-Phase Four-Switch PWM-VSR in d-q Synchronous Frame

用mathematica画的彩色3D的机器猫。(3D color painting with mathematica of Doraemon.)

纯方位跟踪：目标为匀速直线运动模型，可以迅速收敛。(Bearing_only tracking)

本程序可以正常下载，运行。线性分组码定义，对于长度为n的二进制分组码，可以表示成（n，k），通常用于前向纠错。在分组码中，监督位加到信息位之后，形成新码，在编码中，k个信息位，被编为n位长度，（n-k）个监督码的作用是实现检错和纠错。(linear block code)

这个程序是用来设计控制来控制一个平衡水箱的例子。。(This procedure is used to design the control to control an example of a balance tank. .)

严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大， 出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (A Matlab procedures in strict accordance with the BP network computing formula to design, the optimization design was carried out on BP network Optimization design of 1: YYY, that is O (k) in the formula, when the network into the flat area (<0.0001) learning rate increase, after learning rate and reduction Optimization of 2:v (I, J) =v (I, J)+deltv (I, J)+a*dv (I, J) )
