线性局部matlab程序！！！直接可以使用，附加一个解决ppt！(Linear partial matlab program! ! !)

matlab课程编程【谷速软件】matlab从图像中提取字母(matlab programming course speed [Valley] matlab software to extract letters the image)

本程序是一个PN码仿真程序，采用的是matlab/simulink平台进行仿真，源码及数据全都包括在其中。(This program is a PN code simulation program, using matlab/simulink simulation platform, code and data are all included.)

梯度下降法是一個一階最佳化算法，通常也稱為最速下降法。 要使用梯度下降法找到一個函數的局部極小值，必須向函數上當前點對應梯度（或者是近似梯度）的反方向的規定步長距離點進行疊代搜索。如果相反地向梯度正方向疊代進行搜索，則會接近函數的局部極大值點；這個過程則被稱為梯度上升法。(The gradient descent method is a first-order optimization algorithm, also commonly referred to as the steepest descent method. To find the local minimum of a function using the gradient descent method, an iterative search must be performed to the specified step distance point in the opposite direction of the gradient (or approximate gradient) of the current point on the function. If the search is reversed in the opposite direction to the positive direction of the gradient, it will approach the local maximum point of the function; this process is called the gradient ascent method.)

发表在外文会议上的很好的有关人工鱼群算法的文章(Meeting published in the foreign language a good article on artificial fish school algorithm)

说明：  聚类算法MATLAB程序实现，聚类（Cluster）分析是由若干模式（Pattern）组成的，通常，模式是一个度量（Measurement）的向量，或者是多维空间中的一个点。聚类分析以相似性为基础，在一个聚类中的模式之间比不在同一聚类中的模式之间具有更多的相似性。(DBSCAN_Clustering Algorithm)
