orthogonal frequency division multiplexing Matlab code for use

釆用一个二阶系统的模型代替真实系统，其差分方程表达式为： 将此系统在计算机上仿真，输入信号u(k) 是幅值为1 的PRBS 信号，噪声e(k) 是（0，1）的正态分布序列，它的方差是可以调整的。这个系统的输出釆样值z (k) 与u (k) 作为已知数据，采用最小二乘法估计这个系统的参数。 (Preclude the use of a second-order system model instead of the real system, the differential equation expression: this system on a computer simulation, the input signal u (k) is the amplitude of the PRBS signal, and the noise e (k) (0 , 1) the normal distribution of sequence, its variance can be adjusted. The output of this system the Bian samples z (k) and u (k) as known data, the method of least squares to estimate the parameters of this system.)

有关各种光纤光栅的matlab仿真代码，运行正确，可以看到图形(About a variety of fiber grating matlab simulation code, run right, you can see the graphics)

内点法进行最优潮流计算的程序，可以修改目标函数来进行其他不同条件下的最优潮流计算(Interior point method for optimal power flow calculation program, you can modify the objective function for optimal power flow calculation under different conditions)

能用的源码，能正常使用，呵呵，能用，很好用，嗬嗬嗬(The source code can be used can properly use, Oh, can be used, very good use, Ho ho ho)

AN IMPORTANT class of theoretical and practical problems in communication and control is of a statistical nature.

快速的2D/3D区域生长算法，通过对邻近像素进行优先级排队进行加速，效果优于matlab本身的区域生长算法(Native Matlab implementations of region growing algorithms are usually quite slow, especially for 3D input data. This submission is a mex implementation of a 3D/2D region growing algorithm. The region growing process is further accellereated by using priority queues for the neighbourhood pixels.)

使用matlab调用ansys完成优化分析(Call use the matlab optimization analysis ansys)

刚写的Matlab下的M/M/1排队的仿真代码，加了完整的注释(Just write the M/M/1 queue under Matlab simulation code, plus a complete Notes)

基于四叉树分解并且使用区域分离和合并的图像分割(based quadtree decomposition and the use of regional separation and integration of image segmentation)
