brain computer interface matlab code

随机共振相似度的Matlab计算程序，计算看出输入-输出的相似度S随着噪音的标准差的增大而不断得到改善，直到增大至一饱和值为止(an example for SR)

说明：  我最近用MATLAB做的语音处理实验，含有3种处理方式，希望对大家有帮助。(I have recently done with MATLAB voice processing experiments, containing three kinds of approach, I hope all of you help.)

用matlab&spss实现聚类分析,源自《计量地理学》（徐建华，华东师范大学）。(Achieve with matlab & spss cluster analysis.)

说明：  振动信号模态参数识别预处理方法及ITD，STD(NExT method for modal parameter identification of vibration signal)

说明：  uwb脉冲位置调制的信号进行相关接收,并且画出其图形(UWB pulse position modulation signal associated receiver, and draw its graphics)

此代码为本人运用视频读取函数实现视频帧的读取，并可批量转为BMP等格式，另有运动目标静止背景的提取。内附说明文档，欢迎交流。(this code for the use of video I read function video frames to read and can volume to BMP format. another campaign goal from the background static. Enclosing documentation, welcomed the exchange.)

用声卡采集的模拟信号作为输入,然后fft变换,并且图形化的显示出来(sound card collection with the analog signal input, and then fft transform, and the graphics displayed)

牛顿法求解一元三次方程的matlab 的程序，可以在十秒内求解任意一元三次方程(Newton s method for cubic equations)

共包含四个文件： hamo_packet.m 谐波小波包子程序，输入参数为原信号序列，采频，分解层数，返回三维数组，存储各层各频带分解结果； harmopacktest.m 检验上述子程序可行性的m文件； harmonic wavelet analysis.pdf Newland关于谐波小波的原始论文； 20130329谐波滤波.docx 内附matlab程序和分析结果。对电机电流信号做了谐波小波分解，分别从时域和频域构造谐波小波，结果显示，频域构造的小波光滑性稍差。(Contains four files: hamo_packet.m harmonic wavelet buns procedures, input parameters as the original signal sequence mining frequency decomposition level, return to the three-dimensional array, storage layers each band decomposition results harmopacktest.m test subroutine feasibility m-file harmonic wavelet analysis.pdf Newland original papers on harmonic wavelet 20,130,329 harmonic filter the. docx included matlab program and analysis of the results. Harmonic wavelet decomposition of the motor current signal, respectively, from the time domain and frequency domain construct harmonic wavelet, the results show that wavelet smoothing a less frequency-domain structure.)
