QPSK

遗传算法matlab程序，注释详细，适合于初学者学习，采用灾变法避免算法陷入局部最优解(matlab code for genetic algorithm)

SMF-28折射率、群速度、材料色散、波导色散、总色散、包括SMF的基本底层参数。(SMF-28 refractive etc)

tpdf是计算学生t分布概率密度的函数，在金融数值模拟中有广泛应用。(tpdf is calculated Student' s t-distribution probability density function, there are widely used in the numerical simulation of finance.)

说明：  实现BP分类，利用PSO优化BP，换数据可直接运行(Realize BP classification, use PSO to optimize BP, change data to run directly)

说明：  该课题为基于MATLAB的bp神经网络的交通标志识别系统，可以识别禁令标志，警示标志，指示标志三种标志，带GUI界面，流程为，输入测试图，训练，定位，分割，识别。可自动识别是三种中的哪一种。定位是采用颜色的方法，分割是几何位置分割，识别bp神经网络。注释详细。(This project is a traffic sign recognition system based on BP neural network of MATLAB. It can recognize three kinds of signs: prohibition sign, warning sign and indication sign. It has GUI interface. The flow is: input test chart, training, positioning, segmentation and recognition. Which of the three can be automatically identified. The location is based on the color method, and the segmentation is based on the geometric position segmentation to recognize the BP neural network. Note details.)

用MATLAB编写求解伪距定位方程的程序，对实际数据进行处理，解算出接收机的位置及钟差信息。提供8个通道的两组数据如下，X, Y, Z 为WGS-84坐标系下各通道所跟踪卫星的坐标，Range为与之对应的校正后的伪距测量值。(Using MATLAB pseudorange positioning equation solver, and the actual data processing, solution and calculate the position of the receiver clock error information. 8 provides the following two data channels, X, Y, Z coordinates of the WGS-84 coordinate system of each channel of the satellite tracking, Range for the pseudo-range measurements corresponding corrected.)

This package implements basic Principal Component Analysis in Matlab and tests is with grayscale portion of the FERET database. Images are not preprocessed and it is up to the user to preprocess the images as wanted, not changing the filenames.
