FFT程序

说明：  分数傅里叶变换和分数余弦变换，动态展示实部，虚部和模值(Computation of the Fractional Fourier Transform)

轨迹跟踪卡尔曼滤波建立在线性代数和隐马尔可夫模型(hidden Markovmodel)上(The trajectory tracking Calman filter is based on linear algebra and hidden Markov models (hidden, Markovmodel))

：针对三容水箱是较为典型的非线性、时延对象，具有很强的代表性这一特点， 通过机理建模方法建立了三容水箱的一般数学模型。分析了线性和非线性阻力板的流量特性， 并通过实验测定了阻力板流量系数。最后给出了三容水箱的线性化模型。由仿真实验可知，非线性模型的阶跃响应和实验测得的响应曲线相吻合，(: For three-tank water tank is a more typical non-linear, time-delay object, has a strong representation of this characteristic, through the mechanism of modeling methods allow the establishment of three general mathematical model of water tanks. Analysis of linear and nonlinear flow resistance characteristics of plate, and through experimental determination of the resistance plate flow coefficient. Finally, the three-linear model of water tanks. By simulation experiments, we can see that the nonlinear model of step response and the experimentally measured response curve coincide)

Matlab求解微分方程组，几种经典算法(MATLAB Solves Differential Equations, Several Classical Algorithms)

to judge points in a polygon

说明：  基本图论函数库，应用matlab程序，实现路径规划问题(The MatlabBGL library fills a hole in Matlab s suite of algorithms. Namely, it provides a rich set of algorithms to work with graphs, as in graph theory graphs. The MatlabBGL package uses Matlab s native sparse matrix type as a graph and provides algorithms that work)

圆柱绕流边界元程序 用边界元的方法计算圆柱绕流(flow around colomn )

基于abaqus编辑的用户自定义单元，二维四节点单元(the uel for 2d ELEMENT based on abaqus)

在第一个图像中的每个描述符，选择它的匹配到第二个图像。(For efficiency in MATLAB, calculating dot multiplication between unit vectors is faster than Euclidean distance. Please note that: The ratio of attention to angle (the cosine of dot product of unit vector) is the approximate value of the ratio of Euclidean distance of small angle.)
