流形学习的经典短发 ISOMAP 的原代码(classical algorithm of isomap, it is quite useful in manifold learning)

这是我自己写的对图像进行预处理的matlab源程序，主要是对图像进行光照补偿、旋转与尺度归一化。上传上来和大家一起学习、分享。(This is I wrote it myself pretreatment image matlab source, mainly for image illumination compensation, rotation and scale normalized. From up and study together, to share.)

分数阶Lu系统实现,即如何由matlab来实现.(fractionalorderlusystem)

ask调制解调程序，包括序列的产生，加噪，频谱分析，低通滤波输出，抽样判决等(ask modulation and demodulation process, including the sequence generation, noise, spectrum analysis, low-pass filtered output, sample sentences, etc.)

说明：  求取互相关值，可以实现两个序列互相关运算、时延估计等功能。(By calculating the cross-correlation value, the functions of cross-correlation operation and time delay estimation of two sequences can be realized.)

说明：  基于matlab软件的粒子群优化工具箱：psotb-beta-0.3(Matlab software based on particle swarm optimization toolbox: psotb-beta-0.3)

当信噪比较大时，采用广义最小二乘法可能会出现多个局部收敛点，解决这个问题的方法可用多级最小二乘法，一般来说多级最小二乘法包含三级辨识过程。利用输入输出数据，通过多级最小二乘法，可分别求的辅助模型，过程模型和噪声模型的参数估计值。在高噪声的情况下，多级最小二乘法明显优于广义最小二乘法，其收敛点唯一。(When the signal noise ratio (SNR), and by use of the generalized least squares method may appear more local convergence point, the way of solving this problem can be used multistage least squares method, and generally multistage least squares method includes three identification process. Using input/output data, through the multistage least squares, respectively for the auxiliary model, process model and noise model parameter estimation. In the high noise, multistage least squares method is obviously superior to the generalized least squares method, and its convergence point only.)

计算潮流与最优潮流，应用MATLAB，功能相当强大(Load flow and optimal power flow, application of MATLAB, functions quite powerful)
