QpSk Enhanced version on Matlab

this program fits a set of data, using customized function.

用镜像矩阵求出矩阵的QR分解（正交三角分解），并求解线性方程组，该方法不必选主元，但其计算过程非常稳定。也可用于求矩阵的广义逆和求解线性最小二乘问题。子过程QRDCMP用镜像矩阵求m*n矩阵A的QR分解，A=Q^TR,其中Q是m*m正交矩阵，R为m*n上三角矩阵；子过程QRBKSB用矩阵的QR分解求解线性方程组Ax=b，其中A为n阶非奇异方阵。(Matrix obtained with the mirror matrix QR decomposition (orthogonal triangular decomposition), and solving linear equations, the method does not have to choose the main element, but its calculation process is very stable. Can also be used to find the generalized inverse matrix and solving linear least squares problems. Sub-process of the mirror matrix QRDCMP m* n matrix A QR decomposition, A = Q ^ TR, wherein Q is a m* m orthogonal matrix, R is m* n upper triangular matrix subprocess QRBKSB a QR decomposition to solve the matrix linear equations Ax = b, where A is non-singular square matrix of order n.)

有关傅里叶展开式的程序，速度非常快，而且还有相关的实例说明。(About Fourier expansion program, very fast, but also related examples.)

说明：  matlab实现的循环谱估计算法，很实用(Cyclic spectrum estimation algorithm based on MATLAB)

说明：  把信号用数字或符号表示成序列，通过计算机或通用（专用）信号处理设备，用数值计算方法进行各种处理，达到提取有用信息的目的。(The signal using numbers or symbols into a sequence that, through the computer or general-purpose (dedicated) signal processing equipment, numerical calculation using a variety of treatment methods to achieve the purpose of extracting useful information.)

内包括MATLAB初步学习资料，可对初学MATLAB的朋友有一些帮助(Includes MATLAB preliminary study can be found on the MATLAB beginner' s friends have some help)

As a consequence, more exact models of devices can be retained for analysis rather than the approximate models commonly introduced for the sake of computational simplicity. A computer icon appears in the margin with each introduction of MATLAB analysis.

说明：  析了变速恒频双馈风力发电系统的工作原理。结合风力机特性和双馈发电机特性，说明了变速恒频运行方式下的最优风能捕获策略，并介绍了风力发电系统的滑模变结构控制、自适应控制、鲁棒控制和人工神经网络控制。总结了变速恒频风力发电系统的发展趋势。(Analysis of a Variable Speed Constant Frequency Wind Power Generation System works. Combination of wind turbine characteristics and the characteristics of doubly-fed generator, variable speed constant frequency shows the optimal operating mode to capture wind energy strategy, and introduced wind power generation system with variable structure control, adaptive control, robust control and artificial neural networks control. Summarizes the VSCF wind power system trends.)

利用matlab 开发的另一遗传算法工具箱，运行速度快，可选功能多，是一个相当不错的工具箱。(Another development of the use of matlab genetic algorithm toolbox, running fast, many optional features, are a fairly good toolbox.)
