利用四阶亚当斯隐式公式求解常微分方程初值，并计算它与精确解的误差(Using fourth-order implicit Adams formula for solving initial value ordinary differential equations, and calculate the error with the exact solution)

说明：  这是matlab中进行矩阵LU分解的代码。是一个包，集合了模拟LU分解所需的函数文件。(A function for matrix LU factorization.This is the first function.There are another three function named "bslashtx","forward","backsubs".)

采用FDTD方法计算一维空间下，考虑碰撞的等离子体中的电磁场的分布情况(Using the FDTD method for calculating one-dimensional space, the distribution of plasma collision consider electromagnetic fields)

说明：  信号卷积的matlab实现，比较简单的程序，解释清楚易懂，对信号分析的同学会有些帮助(Convolution by matlab)

基于模板匹配的人脸检测教程，matlab代码(tutorial of face detection by template)

说明：  在MATLAB上所使用的PCA程序，主要應用於過濾相對較不重要的特徵值(dimension)，例如在三度空間的某些點具有(x,y,z)值，因為這些點有共同的一個持徵，就是z值相對於x,y值來得小很多(不明顯)，所以就以X,Y軸來表示這些點。此時就達成去除掉z的特徵值(dimension)。 (MATLAB used in the PCA procedure, mainly used in filtering relatively unimportant eigenvalue (dimension), for example, in some points with three-dimensional (x, y, z) values, because these points have a common one sign holders, that is, z values compared with the x, y values much smaller than (not obvious), so on to X, Y axis to express these points. Reached at this time to get rid of z eigenvalues (dimension).)
