主要是希尔伯特——黄HHT中的EMD分解过程的工具箱，将其导入matlab的工具箱中，就能使用！(Mainly Hilbert- Huang HHT in the toolbox EMD decomposition process will import the toolbox matlab, you can use!)

说明：  Matlab数学建模程序包，数学建模型竞赛必备武器(Matlab package for mathematical modeling, mathematical model of arms race must)

除氧器计算,主要用于除氧器蒸汽耗量计算，简单准确(pipe design)

蚁群算法用于TSP问题的matlab程序源代码(Ant colony algorithm for TSP problem of matlab source code)

a simple code for plot some kinds of geophysical data (such shot, CMP,... gathers).

matlab主成分分析的几个案例 包括从协方差矩阵或相关系数矩阵出发求解主成分 从样本观测值矩阵出发求解主成分(Principal component analysis matlab several cases, including the covariance matrix or correlation matrix to solve the main ingredient of departure from the starting sample observation matrix solving the main ingredient)

展频PLL时钟（SSC）产生电路，可以产生三角波、正弦波或者单频载波(Delta_Sigma Modulator, to be used in TXPLL with SSC modulation. this program simulates the Spread spetrum clocking scheme. the SSC can be set to triangle wave or sinewave, or you can also set it to be constant frequency which without SSC. the relevant parameters is programmable. )

说明：  通过 matlab 编程实现捷联惯导系统初始对准、惯导解算的全过程。 1）初始自对准：利用前10分钟实验车静止的数据进行惯导系统的自对准。采用前2分钟数据进行解析粗对准，后8分钟数据用五状态Kalman滤波器实现精对准；为了验证精对准性能，可在粗对准结果上把航向角人为加一定幅度（如10度）的误差，观察精对准的收敛性能。 2）纯惯导解算：对准结束后转入纯惯性导航解算，要求进行双子样的圆锥和划摇补偿，即每20ms完成一次导航解算，输出完整的导航结果包括三个姿态、两个水平速度和两个水平位置（天向通道发散不必输出），并给出姿态、速度、位置随时间的变化曲线以及位置误差曲线。(The whole process of initial alignment and inertial navigation solution of strapdown inertial navigation system is realized by matlab programming.)

A cyclic redundancy check (CRC) is an error-detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. Blocks of data entering these systems get a short check value attached, derived from the remainder of a polynomial division of their contents on retrieval the calculation is repeated, and corrective action can be taken against presumed data corruption if the check values do not match.

这是两个用matlab实现最小生成树的算法源代码，希望对大家有帮助。(This is a two matlab to achieve the minimum spanning tree algorithm source code, we hope to help.)
