kalman filter in matlab package, very wide and practical

说明：  航海与气像学讲义，讲述海洋学与气候关系，初学者有帮助，请下载(Navigation and gas as the school notes, about the relationship between oceanography and climate, beginners help, please download)

该代码能够实现改进的线性调频Z变换的功能，取代FFT变换能够起到细化频谱的作用。(The code can achieve improved chirp Z transform function, replace the FFT spectrum can play a role in refinement.)

dem差值计算，给定基础网格高程对相应空间迭代差值获得网格高程(dem difference calculation, given the appropriate space on the basis of the grid elevation difference of iterations to get the grid elevation)

matlab code for noise removal

图像的反转，灰度线性变换，非线性变换，直方图均衡化，中值滤波，梯度算子检测边缘等，，(The reversal of the image, the gray linear transformation and non-linear transformation, histogram equalization, median filtering, edge detection and so on, the gradient operator, )

matlab判别分析，基本思想是将高维的模式样本投影到最佳鉴别矢量空间，以达到抽取分类信息和压缩特征空间维数的效果，投影后保证模式样本在新的子空间有最大的类间距离和最小的类内距离，即模式在该空间中有最佳的可分离性。(matlab discriminant analysis, the basic idea is to sample the high-dimensional pattern projected onto the optimal discriminant vector space, in order to achieve the classification of information extraction and compression feature space dimension effect, the projected sample assurance model in the new subspace has the largest class room the intra-class distance and the minimum distance, i.e., have the best separability pattern in the space.)
