使用matlab分析传统光学系统中加入三次相位掩模板之后其点扩散函数的焦点偏移(Analysis using matlab conventional optical system by adding three phase mask after the point spread function of its shift in focus)

Partition index is a measure ofvalidity similar to partition coeGcient, based on using Pj = ci=1 (uij)m as a measure ofhow well the jth data point has been classi- 2ed. The closer a pixel is to a codebook entry, the closer Pj is to one. Ifa pixel becomes an outlier to all cluster centers, the value of Pj approaches 1=cm − 1, which is the minimum value it can have.

This is PAPR for CPM-SC-FDMA

matlab编写的程序，分别实现了一维线性调频信号，二维线性调频信号，脉冲压缩，过采样率对频谱的影响，加窗 的仿真(the matlab programs written, respectively, to achieve the one-dimensional linear FM signal, two-dimensional linear FM signal pulse compression the oversampling ratio spectrum windowed simulation)

说明：  偏最小二乘法中的交叉有效性计算的matlab程序，怎么计算出来的预测误差平方和PRESS不太对，偏大；()

使用matlab编辑文本并输出，作为Parmela的输入文件，同时通过matlab的Dos功能执行粒子模拟计算，节约时间。(Edit text using matlab and output, as the input file Parmela through Dos function matlab implementation of the particle simulation, saving time.)

关于演示旋转的一个应用程序，可以更好的理解体旋转的过程(The project is made by using GUIDE of Matlab 7.5.0 (R2007b) and user-defined classes. The project may be used on the seminars on mechanics in the technical educational establishments. Rigid body section of a course of mechanics is considered as required in most technical colleges and Universities. Sometimes it s difficult to imagine a rotation of a rigid body in the three-dimensional space. Especially, when an asymmetric top is in question. Rigid Body project may help students to see the rotations clearly as though they were in the real world. Author of Rigid Body project: Ferat Talat oglu )
