coding for FVM-based numerical solution

卷积码的编码器是由一个有k个输入端、n个输出端、m节移位寄存器所构成的有限状态的有记忆系统，通常称它为时序网络。(A convolutional code encoder is composed of a k-th input terminal of the n output terminals, m section shift register constituted by a finite state memory system, the usually call timing network.)

通过运用matlab软件对图像进行直方图处理，从而达到处理的效果(By using matlab software for image histogram processing, so as to achieve the effect of treatment)

QAM，(正交振幅键控调制)，输出为QAM调制产生的复包络信号(QAM, (quadrature amplitude modulation keying), QAM modulation output generated by complex envelope signal)

Thickness of Various effectiveness of materials

color thresholding. this code very usefull

用于对复杂流场的POD分析，对流场结构进行解构重组(PODDEM is a state of the art detection and estimation method for outliers in Particle Image Velocimetry data. PODDEM can be used on two-dimension and three dimensional data, with up to three velocity components.)

ML法能够很好的估计信号的信噪比,MIMO OFDM matlab仿真,欢迎大家下载学习。( ML estimation method can be a good signal to noise ratio, MIMO OFDM matlab simulation, Welcome to download the study.)

正交最小二乘辨识算法 该算法除了实现最小二乘辨识功能之外而且能按照各项重要性将其逐一选出并且估计相应系数(OLS Orthogonal Least Quares. [x, ind] = OLS(A,b,r) gives the solution to the least squares problem using only the best r regressors chosen from the ones present in matrix A. This function also returns in the vector ind the indexes of the best r regressors (i.e., the best columns of A to use). If r is equal to n, the solution x given by OLS is the same as the solution given by A, but in ind we still have the regressors sorted by their importance. This means that one can perform a feature selection by taking the first k entries in ind (k<r).)
