matlab-(2)

一些常用的matlab代码，比如线性规划和解方程，各种拟合等(Some commonly used matlab code, such as linear programming reconciliation equation, a variety of fitting)

STBCQPSK仿真程序,shihechuxuezhe(simulationprogramforSTBCQPSK)

此程序能实现很好的低通滤波，能很好的滤除低频分量，对于初学图像处理的人很有用(This process can achieve a good low-pass filtering, the filter can be a very good low-frequency components, for beginners who are useful image processing)

利用matlab实现下面的问题：其中u(k)和z(k)分别为模型的输入和输出变量；v(k)为零均值、方差为1、服从正态分布的白噪声；为噪声的标准差；利用得到的u(k)和z(k)来辨识模型的阶次和参数。　　(Using matlab to achieve the following questions: where u (k) and z (k) respectively, the input and output variables of the model v (k) with zero mean and variance 1, follow a normal white noise noise standards Poor utilization u (k) and z (k) to identify the order and parameters of the model.)

高精度的matlab求微分方程组的边值问题的bvp6 c的解算器，精度高于常用的bvp4c。(bvp6c solver for ode bvps in matlab)

通过正弦函数实现的光通信应用的占空比为50％或33％的RZ－DPSK信号(Sine function through the implementation of optical communication applications, the duty cycle of 50 or 33 RZ-DPSK signal)

DS的信号调制解调，是基于matlab的的M文件。(DS signal modulation and demodulation, is based on the M-file matlab.)

说明：  求均方根值,可以用在求图像或者求频谱的时候应用。(solve the square)

Matlab_曲面插值和拟合，dajie可以看看(something about Matlab_b-spline)

两个站点的测向交叉定位的三维GDOP仿真(triangle GDOP)
