是对fft进行分析的电子书，利用matlab.(this book is a introduction for FFT with matlab)

说明：  Iris数据集的分类程序，包括线性分类器实验，BP网络分类器实验，以及异或数据的BP网络分类实验，外带试验报告(Iris data set of classification procedures, including linear classification experiment, BP network classifier experiments, and different BP networks or data classification experiment, take-test report)

这是一个图像信噪比计算的小程序，不是峰值信噪比，请注意。(This is a small program SNR calculation, not the peak signal to noise ratio, please note.)

奇异值与主成分分析（PCA)的介绍,比较简明易懂,对初学人大有帮助(SVDAND PCA,HOPE TO HELP YOU,IF YOU HAVE SOME QUESTION ASK ME)

录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；通过matlab界面进行编程设计，界面方便人们操作( Their record a voice signal, and recording the signal is sampled draw sample after the time-domain waveform and frequency spectrum of the speech signal designed by matlab programming interface, easy for people to interface)

development package based OpenSceneGraphics libary for Geology.

说明：  震动信号处理的相关函数和使用测试，来源于教材(The correlation function and application test of vibration signal processing come from teaching materials)

根据已给ecg数据文件，画出心电图波形，并自动标记出特征点位置，并计算P-R时间间隔 等参数。 附件是.dat为数据文件，为二进制文件，每2个字节代表一个采样点，采样频率1000hz。依 次为1-12导联的第一个采样点，其次是1-12导联第二个采样点，.... .hea头文件是文本格式说明文件，可以看到十二导联存放的先后顺序。 (According to the data file has to ecg, draw the ECG waveform, and automatically mark the feature points, and calculate parameters such as PR interval. The attachment is. Dat for data files, binary files, each 2 bytes represent a sampling point, the sampling frequency 1000hz. Followed by a 1-12 lead in the first sampling point, followed by 1-12 second sampling point lead ,..... Hea header file is a text file format that you can see the sequence)

系统辨识，根据最小二乘法，辨识出系统参数，达到优化参数的效果。(.System identification, according to the least squares method, identify the system parameters, to achieve the effect of optimization parameters)
