NLSE用于求解偏微分方程 可演示非线性光纤光学任何一个方程(NLSE pian weifen fang cheng qiu jie guang xian guang xue yan shi cheng xu ke jie ren he yi ge pain wei fen fang cheng )

自己编写子空间拟合进行DOA估计，包括信号子空间拟合，噪声子空间拟合。malab程序，效果很好！( )

说明：  基于Harris的掌纹图像特征提取的程序，非常的完整可靠(Harris based on palmprint image feature extraction procedures, very full and reliable)

用平面波展开法计算的二维光子晶体结构例程三，matlab程序源代码(With the plane wave expansion method to calculate the three-dimensional photonic crystal structure routines, matlab source code)

说明：  日本科学家奥村通过对城市进行大量无线电波传播损耗的测量，得出了一系列经验曲线用于无线蜂窝网络的规划设计。在这些经验曲线的基础上，推出了简化的Hata模型。(Olympic Village by Japanese scientists a great deal of radio waves in urban propagation loss measurement, the experience curve obtained for a series of planning and design of wireless cellular networks. In the curves on the basis of these experiences, the introduction of a simplified Hata model.)

图片快速傅里叶变换 灰度转换 FFT坐标(FFt for images)

PLS GIVE MATLAB CODING

滤波程序，用于信号处理中的滤波分析，希望对大家有用(very good，useful)

无心磨削优化，主要用于工程计算，工程优化。(Grinding optimization, is mainly used for engineering calculations, engineering optimization.)

this code is about mlp 1 layer neural network with back propagation training algorithm by using geradient descence for nonlinear system. input data are random.
