求解二维圆柱绕流问题，涉及坐标变换，还有通量分裂，在变坐标系下直接数值模拟ns方程二维情况(Solving two-dimensional circular cylinder flow problem, involving the coordinate transformation, flux splitting, direct numerical simulation ns Fang Cheng Erwei situation in the change of coordinate system)

这是对广义高斯分布中两个参数alpha,beta的估计方法，对自然图像的大量统计特征就符合这一分布。(function [f, g] = dggbeta(beta, absx) DGGBETA Derivative of generalized Gaussian pdf with respective to beta [F, G] = DGGBETA(BETA, ABSX) Return partial derivative and second order partial derivative This is an utility function for GGMLE ABSX is the distance of the data from the mean Function is undefined for negative beta if beta <= 0 f = NaN g = NaN )

Fisherface方法的实现是在PCA数据重构的基础上完成的，首先利用PCA将高维数据投影到低维特征脸子空间，然后再在这个低维特征脸子空间上用LDA特征提取方法得到Fisherface。程序中使用参数寻优的方法来寻找最佳投影维数，以达到比较理想的识别效果。 (The Fisherface method implemented in the PCA data reconstruction based on the completion of the first use of PCA projection of high-dimensional data to a low dimensional feature subspace, and then on the characteristics of low-dimensional subspace LDA feature extraction methods to get the Fisherface. Program parameter optimization method is used to find the best projection dimension, in order to achieve the ideal identification.)

关于Matlab的学习资料，这是其中的一部分，很不错的。(Matlab information on learning, which is a part, it is good.)

很好的学习FFT的程序，易于理解，便于学习，具有很好的参考价值(Learning the FFT program, easy to understand, easy to learn, have a good reference value)

这是一个矢量控制成功mdl模型，可改编为任何电机（永磁同步电机 异步电机等），低版本matlab上编写，大家均可成功运行 (Vector Control；PMSM Induction motor；mdl)
