matlab在大气科学中的应用~这是介绍如何在大气科学研究中使用matlab的入门教程(matlab in atmospheric science applications- this is how to use matlab in atmospheric sciences Tutorial)

常用信号分析程序，包括FFT，画包络谱，频谱，自相关、互相关，倒频谱，功率谱(Common signal analysis program, including FFT, painting envelope spectrum, spectrum, auto-correlation, cross correlation, cepstrum, power spectrum)

说明：  这是基于mutlab编写的最新支持向量机程序源码(This is based on the latest mutlab write program source code support vector machines)

this is only parameters to DFOC of induction machines and file to start

利用matlab 做拟合的图表 两个序列进行拟合 并画出拟合后的图和残差 另外作图的过程是每次都取相同的一段数据 且起始点不断往后推(Using matlab to do a chart to fit the proposed merger of two sequences and residual process diagram plotting another draw after fitting is always take the same piece of data and constantly pushed back the starting point)

说明：  root music 算法估计精度更加优秀(root music The estimation accuracy of the algorithm is better)

本程序采用matlab编写，可以用来识别车牌号码，识别是比较好的(This procedure uses matlab preparation, can be used to identify the license plate number, identification is a better)

PEAK FINDER to find the peaks in a spectrum

双站交叉定位误差展示程序 产生观测数据 假设被定位对象匀速地从A点(dx1,dy1)运动到B点(dx2,dy2)，单位：km 使用速度输入V(km/h)，则dx2=V*t，t为观测时长(h) dy1=dy2=R，目标距离 假设采样时间间隔为1h(Bistatic cross-positioning errors show program)

In linear algebra, Gaussian elimination (also known as row reduction) is an algorithm for solving systems of linear equations. It is usually understood as a sequence of operations performed on the associated matrix of coefficients. This method can also be used to find the rank of a matrix, to calculate the determinant of a matrix, and to calculate the inverse of an invertible square matrix. The method is named after Carl Friedrich Gauss, although it was known to Chinese mathematicians as early as 179 AD (see History section).
