认知无线电的频谱检测算法的MATLAB实现，完整版。(Cognitive radio spectrum detection algorithm of the MATLAB realization of the full version.)

使用每秒10个采样的频率 ，对信号 进行采样，画出原始信号的傅立叶变换X(f) 和理想采样信号的傅立叶变换 。假定重构滤波器是带宽为 的理想低通滤波器，具有带通增益 ，画出重构滤波器的输出(Using 10 samples per second frequency, the signal is sampled, to draw the original signal Fourier transform X (f) and the ideal sampling signal Fourier transform. Reconstruction filter is assumed that the ideal bandwidth low-pass filter with a bandpass gain, draw the output of reconstruction filter)

说明：  先用.txt文件导出杆系结构和梁系结构的用于节点校核的数据，然后用matlab程序计算即可进行构件验算(time. Txt file is derived bar structure and the structure of the beam system for checking the data node, then Matlab can be calculated for checking Component)

the program to run example

matlab计算曲率，包括主曲率，高斯曲率和平均曲率的计算方法，测试可用。(matlab computing curvature calculation methods including principal curvatures, Gaussian curvature and mean curvature of the test are available.)

根据MATLAB的语言组织形式来编排，主要是用来实现预测编码和解码作用(DPCM)

该程序是用ＭＡＴＬＡＢ语言编写的符合３ＧＰＰＰ标准的ＴＵＲＢＯ编码内交织器．(that the procedure was used to prepare the MATLAB with 3GPPP Turbo coding standards within intertwined device.)

一阶熵、二阶熵和差分熵c++程序 求熵用的 (A first order, second order entropy and entropy difference entropy ofc++ program)

运动捕获数据周期运动，用于做运动分割或关键帧提取(Motion capture data periodic motion, used to make motion segmentation or keyframe extraction)

说明：  基于MATLAB车牌识别的应用，请大家多多指教(Application of MATLAB-based license plate recognition, please bear teach)
