说明：  基于当前统计模型的matlab程序仿真实现(Statistical model based on the current simulation matlab program to achieve)

说明：  原代码包括捷联惯导初始对准程序,实用性强,便于学习(chushiduizhun)

在bate1版的基础上： 增加了关闭某条便笺时，记忆某条便笺的位置和大小的功能。 跟随窗体的按钮不再会溢出 改变了帮助文本的样式 在帮助中添加了作者信息 便笺的默认储存位置从原来的 D:\_NOTE_TEMP 更改为了 现在的 D:Program Filesakai_note 优化了使用过程中的说明与提示 临时文件单独存放与临时文件夹 解决了退出编辑状态时，部分时候文本不能换行显示的问题 akai 2011 from PHY. of CCNU 2013-2-22 ========================================= 在bate2版的基础上： 产品名由原来的 akai_note 改为 ackeline_note 便笺的默认储存位置从原来的 D:Program Filesakai_note 改为：D:Program Filesackeline_note 增加了便笺可以更改颜色的功能，六种颜色随心选！ akai 2011 from PHY. of CCNU 2013-2-22 =========================================(In the version on the basis of bate1: Increased when closing a bar notes, location and size of the function of memory in a memo. Follow the form of the button will no longer overflow Change the help text styles With the help of information added to The default storage location notes from the original D: _ NOTE_TEMP change order Now the D: Program Files akai_note Optimize the use of the process instructions and tips Separate storage of temporary files and temporary files folder Solve the exit edit state, some time can not wrap text display issues akai 2011 from PHY. of CCNU 2013-2-22 ========================================= Based on the version of the bate2: Product name changed from the original akai_note ackeline_note The default storage location notes from the original D: Program Files akai_note Read: D: Program Fi)

设关系A是从集合X={1，2，….，n}到集合Y={1，2，…..，m}的二元关系，而关系B是从集合Y到集合Z={1，2，….，p}的二元关系，求A与B的合成关系C。(A relationship is established from the set X = (1,2, ...., N) to the collection Y = (1,2, ... .., m) of binary relations, the relationship B is from a collection of Y to the set Z = ( 1,2, ...., p) of the binary relation, find the relationship between A and B, synthesis of C.)

利用matlab模拟光纤中的HE11模的模式分布图。(Using matlab to simulate the HE11 mode fiber mode distribution.)

说明：  按FPE定阶的 源程序：fpe.cpp M序列：M序列.txt 白噪声：Gauss.txt 程序中先用依模型阶次递推算法估计模型的参数，再用fpe方法判断模型的阶次。 程序运行结果如下： n: 1 判断阶次FPE的值: 0.0096406 -0.481665 1.07868 n: 2 判断阶次FPE的值: 0.00875755 -0.446739 0.00498181 1.07791 0.0527289 n: 3 判断阶次FPE的值: 0.0087098 -0.459433 0.120972 -0.0569228 1.07814 0.0390757 0.116982 n: 4 判断阶次FPE的值: 0.000396884 -0.509677 0.4501 -0.200906 0.0656188 1.07991 -0.0156362 0.442989 0.0497236 n: 5 判断阶次FPE的值: 3.2095e-007 -1.18415 0.813123 -0.517862 0.34881 -0.116864 1.07999 -0.744141 0.474462 -0.253112 0.122771 n: 6 判断阶次FPE的值: 3.23349e-007 -1.14659 0.76933 -0.487651 0.329676 -0.10377 -0.00440907 1.07999 -0.703574 0.447253 -0.235282 0.113587 0.00479688 从以上结果可以看出，当n=5时，fpe值最小，所以这时的模型阶次和参数估计值为最优结果： 3.2095e-007 -1.18415 0.813123 -0.517862 0.34881 -0.116864 1.07999 -0.744141 0.474462 -0.253112 0.122771(err)
