常规波束形成，均匀加权，给个权重因子，线列阵常规波束形成。(Conventional beamforming, uniform weighting, to a weight factor, the conventional line array beamforming.)

对语音信号进行分帧处理，输入需要被分帧的语音信号和所需帧长和帧移，即可对语音信号进行分帧处理(The program is used for framing of speech)

说明：  在vc中调用matlib得时候，需要一些引擎文件，在这里已经全部包含。(in vc call matlib in time and need some engines, has been here all included.)

FIR滤波器设计文件，编写为function，便于修改调用，欢迎下载使用(FIR filter design document, prepared for the function, called facilitate change, welcomed downloading)

用平面波展开法计算二维声子晶体带隙，里面附有注释，可以学习(With two-dimensional plane wave expansion method to calculate the phononic band gap, which is annotated, you can learn)

归一化倒谱提升窗口 预加重滤波器 语音信号分帧 计算每帧的MFCC参数 (Calculate the audio files of the MFCC factor)

说明：  UUV 6自由度模型代码，仿真实例。。。。(Verification of a six-degree of freedom simulation model for REMUS autonomous underwater vehicles.)

阈值法区造程序，包括软阈值和硬阈值，还有软硬这种法去噪的程序(Threshold area making process, including the soft threshold and hard threshold, as well as soft and hard process of this method de-noising)
