- Stone column play important role in infrastructure, improving soft soil. The behaviour of stone column, however, remains far well understood

说明：  用平面波展开法计算二维二组元圆柱散射体型声子晶体能带结构的matlab代码。(This matlab code uses PWE to calculate the band structure of 2-D phononic crystal with cylinder scatterer.)

這是一個類神經網路中倒傳遞類神經網路，應用於圖形識別上，可以把兩個不同分類的點，藉由BP找出他的分割線進行區分(This is a type of neural network back-propagation neural network applied to pattern recognition, it can be classified into two different points, by BP to find his distinction between partition lines)

用matlab实现了数字信号处理中的多采样转换，并依此原理进行采样转换滤波器的设计。(matlab)

基于双端电气量的故障测距，里面的输电线路是分布式输电线路，所以该模型已经考虑到了分布参数对测距的影响，能进行稳定而精确的测距！(Based on samples at both ends of the fault location, inside the transmission line is a distributed transmission line, so that the model has taken into account the effect of the distribution parameters ranging, enabling stable and accurate distance!)

esprit algorithm for estimation of DOA

编码开关源代码，实现音响的音量控制前级输入，(Coding switch the source code to achieve sound volume control preamplifier input,)

说明：  matlab 人脸识别的源文件，。，，，，。。。。(matlab m files )

Principal component analysis

求插值逼近的matlab程序非常有用，而且运行速率比较快。非常不错。(Find interpolation approximation matlab program very useful and run faster rate. Very good.)
