SSIM 1.0 Local Search Similarity

利用VC和Matlab混合编程,Release文件夹下可直接运行，绘出2D和3D图形。并且可以在VC 6.0环境下调试，注意文件夹中的readme文档说明。(Using VC and Matlab to program, Release folder can be run directly, draw 2D and 3D graphics. And it can debugging in VC 6.0 environment, pay attention to the folder readme documentation.)

说明：  bp神经网络实现预测，已经在鸢尾花数据集中验证过，拟合能力不错(Prediction of BP neural network)

This file is the matlab code related to the imaging.

用于产生风速，基于kaimal谱分析建立。(This submission allow the user for generation of three-dimensional turbulent wind fields, by employing a Kaimal spectrum and IEC-based coherence function. Furthermore, it is possible to export the generated wind fields as FAST-compatible .bts, in order to simulate wind turbine dynamic behavior in presence of stochastic wind. )

计算三维坐标各点相互距离，结果存在对角阵中(calculate 3D points distance between eachother!)

kuanjiange_seq.m 基于对偶频带法和m序列，产生一个宽间隔跳频序列。 kuanjiange_seqencezu.m 基于对偶频带法和m序列，产生一个宽间隔跳频序列族。 注：其中的m序列是利用三个非相邻级控制频率合成器构造 L_G模型。(kuanjiange_seq.m based on dual band m sequence, have a wide interval frequency hopping sequence. Kuanjiange_seqencezu.m based on dual band and m sequence, have a wide interval frequency hopping sequences. Note : The use of m-sequences are non-adjacent three-level control frequency synthesizer L_G tectonic model.)
