Colorsegmentation

It is a drilling system control

半正定矩阵cholesky方法将其分解为两个上下三角矩阵相乘的形式。matlab自带的函数只能分解正定矩阵。并且给出例子。(Semi-definite matrix cholesky method be decomposed into two upper and lower triangular matrices form. matlab built-in function can only be positive definite matrix decomposition.)

改程序是用MATLAB写的有关运动背景补偿的算法(Reform program is about the background motion compensation written using MATLAB algorithm)

主要包括用重标极差法计算Hurst指数并绘制双对数图(Including the rescaled range method (R/S analysis) to calculate Hurst exponent, function and caller)

说明：  MIMO信道仿真用于OFDM系统，完整代码(MIMO channel simulation for OFDM system)

ofdm发送端和接收端，根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。(ofdm sending end and receiving end, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives.)

FSK调制模型，提倡共享。谢谢大家支持。(FSK modulation model, promoting sharing. Thank you for support. Thank you, Thank you, thank)

对周期性信号进行循环谱估计，非常实用的代码！！(Cycle of the periodic signal spectrum estimation, a very useful code! !)

本文详细的介绍了FM信号产生和接收的方法，并给出了详细的matlab程序(producing and receiving FM signals)

matlab程序运行时导入数据文件作为输入参数，三相光伏逆变并网的仿真，BP神经网络的整个训练过程。( Import data files as input parameters matlab program is running, Three-phase photovoltaic inverter and network simulation, The entire training process BP neural network.)
