小球下落建模可调整参数,以变为上抛,绘出小球路线,动画显示.绝对原创(Modeling the fate of small-ball adjustable parameters in order to throw up into, small ball route map, animation show.)

这是一本经典的MatlAB书的实验代码，非常丰富，非常实用(This is a classic book of experimental code MatlAB, very rich, very practical)

非常好的MATLAB教程，当你看完教程后你会发现MATLAB比其它开发语言要简单的多(MATLAB tutorial is very good, when you read the tutorial you will find MATLAB simpler than other development languages ​ ​ to)

说明：  对雷达射频端实施射频噪声干扰，观测雷达目标回波干扰情况。给出了具体的matlab源码，和效果图。(Radio frequency noise jamming is applied to the radio frequency end of the radar, and radar target echo jamming is observed. The specific matlab source code and the effect diagram are given.)

多个脉冲积累后可以有效地提高信噪比，中频积累时要求信号间有严格的相位关系，即信号时相参的，所以称为相参积累。(Multiple pulse accumulation can effectively improve SNR, if integration requires strict phase relationship between signals, whereby the signal coherent, so called coherent accumulation.)

这是一个关于极限学习机matlab的核函数的源程序，对有这方面研究的人有帮助(this is a matlab source program of elm)

利用matlab 做拟合的图表 两个序列进行拟合 并画出拟合后的图和残差 另外作图的过程是每次都取相同的一段数据 且起始点不断往后推(Using matlab to do a chart to fit the proposed merger of two sequences and residual process diagram plotting another draw after fitting is always take the same piece of data and constantly pushed back the starting point)

用matlab实现DQPSK的调制解调，并绘制BER曲线(Using matlab to achieve DQPSK modulation and demodulation, and draw the BER curves)

局部最小距离分类器，性能高于knn分类器，matlab环境下，可直接调用(Local minimum distance classifier, classifier performance than knn, matlab environment, can be called directly)

全面分析机械类个企业的经济效益，以一家公司的盈利额为研究对象，选择了8个不同的利润指标，14企业关于这8个指标的统计数据如下表所示，试进行主成分分析。(Comprehensive analysis of the economic efficiency of enterprises machinery months to a company' s earnings amounted research object, select 8 different profit targets, 14 companies on these eight indicators of statistical data in the following table and try to principal component analysis.)
