PID-MATLAB

说明：  bp神经网络的源程序，很实用，很不错的！(bp neural network source code, very practical, very good!)

说明：  小波分解，另附有图片，下下来即可用 小波分解，另附有图片，下下来即可用(Decomposition, attached pictures, you can use the wavelet decomposition down under, attached pictures, you can use the next down)

在非理想情况下，在对经纬度实施更新的情况下，一直长度，求速度。(In the ideal case, the latitude and longitude of implementing the update situation, has length, and speed.)

基于粗糙集的模糊分类模型的MATLAB代码。可用(MATLAB code based on fuzzy rough set classification model. Available)

采用PCA提取人脸特征,先计算M个图像的平均值脸，再求出各特征值脸。(Using PCA for face feature extraction, first calculate the average face image of M, and then find the face value of each characteristic.)

有关求解微分方程的代码 常微分方程的matlab解法(using matlab to solve normal differential equations)

Determines azimuth angle in all sky imager images.

经典的Adaboost分类器训练过程详细的matlab代码解释，对做模式识别的人很有用(Classic Adaboost classifier training process explained in detail matlab code, to do pattern recognition is useful)

说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)

A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is a part of the biometric identification methodologies which also include facial, fingerprint, palm and many other biological traits. They all offer new solutions for person identification, authentication and security. Currently users have to carry security badges or know certain pin/pass codes in order to get into secure zones or to log into a computer. In this paper we propose an algorithm for iris recognition, which can be applied in real time with standard webcam and with good matching result.
