FFT

基于蒙特卡罗方法的试卷难度分布研究,Monte Carlo method based on the difficulty of distribution of papers(Monte Carlo method based on the difficulty of distribution of papers)

说明：  Matlab教程，可以借助其学习和使用Matlab，使用软件过程中还可以查阅。(Matlab tutorials can make use of their learning and the use of Matlab, using the software process can access.)

运用MATLAB求解偏微分方程的数值解的程序(Numerical Solution of Partial Differential Equations MATLAB program)

说明：  声波方程正演模拟小模型波场绘制。只有一层，震源在中间。C程序，Matlab绘图。(Acoustic wave equation forward modeling small-scale model wave field rendering. Only one layer, source in the middle. C program, Matlab graphics.)

说明：   有一个长度为整数L(1<=L<=10000)的马路，可以想象成数轴上长度为L的一个线段，起点是坐标原点，在每个整数坐标点有一棵树，即在0,1,2，...，L共L+1个位置上有L+1棵树。 现在要移走一些树，移走的树的区间用一对数字表示，如 100 200表示移走从100到200之间（包括端点）所有的树。 可能有M(1<=M<=100)个区间，区间之间可能有重叠。现在要求移走所有区间的树之后剩下的树的个数。 输入： 两个整数L(1<=L<=10000)和M(1<=M<=100)。 接下来有M组整数，每组有一对数字。 输出： 可能有多组输入数据，对于每组输入数据，输出一个数，表示移走所有区间的树之后剩下的树的个数。(Has a length of integer L (1 &lt = L &lt = 10000) of the road, one can imagine a number line segment of length L, the starting point is the coordinate origin, each integer coordinate points in a tree, i.e. 0,1 , 2, ..., L total has L+1 L+1 positions on the tree. Now to remove some trees, tree removed by a range of digitally represented, such as 100 200 represents removed (inclusive) between 100 and 200 all the trees. There may be M (1 &lt = M &lt = 100) intervals, there may be overlap between the intervals. Now, after the number of trees require the removal of all remaining sections of the tree. Input: two integer L (1 &lt = L &lt = 10000) and M (1 &lt = M &lt = 100). Then there is an integer M groups, each with a pair of numbers. Output: there may be multiple sets of input data, for each set of input data, the output of a number indicating the number of the removal of all remaining sections of the tree after tree.)

将加速度积分成速度位移，并且滤波，很好用(Displacement velocity integral of the acceleration and filtering, the good)

使用Crank-Nicolson隐式差分格式求解传热方程；第一类边界条件；初始条件已知。(Using the Crank-Nicolson implicit difference scheme for solving heat transfer equation the first boundary condition initial conditions are known.)

THIS IS THE MATLAB CODE FOR PTS TO REDUCE PAPR

关于链表的实现例子很完美呵呵要的朋友请下哦！！！(With regard to the realization of the list is a perfect example of a friend to call on the next Hehe Oh! ! !)
