Tamir模型的源代码,主要研究在树林信号传播时的衰减模型。(The Tamir model source code, mainly in the woods signal propagation attenuation model.)

说明：  使用一种方法来产生一组具有不同PSD的相关高斯过程的采样值(Use a method to generate a set of different Gaussian process of PSD-related samples)

在MATLAB下实现模糊综合评价，有GUI用户界面，例子为打分系统，为初学者提供帮助。 简介：模糊综合评价法是一种基于模糊数学的综合评标方法。该综合评价法根据模糊数学的隶属度理论把定性评价转化为定量评价，即用模糊数学对受到多种因素制约的事物或对象做出一个总体的评价。它具有结果清晰，系统性强的特点，能较好地解决模糊的、难以量化的问题，适合各种非确定性问题的解决。(Achieved in MATLAB comprehensive uation, there are GUI user interface, examples of scoring system, for beginners to help. Profile: fuzzy comprehensive uation is a comprehensive uation method based on fuzzy mathematics. The comprehensive uation method based on the theory of fuzzy membership of the qualitative uation into quantitative uation, which uses fuzzy mathematics by a variety of factors thing or object to make an overall uation. It has a clear result, systematic and strong features, it can solve vague, difficult to quantify the problem, for solving the problem of non-deterministic.)

利用周期图法对序列的功率谱进行估计。数据窗采用汉明窗。假设在白噪声中分辨这三个不同频率的正弦信号,其相位是均匀分布在2PI的独立随机变量,而 是一个单位白噪声.生成50个长度为N=512的 的样本序列集合。 (use map cycle sequencing method of the power spectrum estimation. Data window using Hamming window. Assume that the white noise to differentiate between the three different frequency sinusoidal signal, its phase is uniformly distributed in the PI two independent random variables. but a flat white noise. Generating 50 length N = 512 samples of the sequence set.)

生成指定概率分布的随机数，可用于数学与金融的随机分析(Specify the probability distribution of randomly generated number, can be used for the stochastic analysis and financial mathematics)

独立向量分析（IVA）是对独立成分分析（ICA）算法的一种扩展，将ICA中的单变量成分扩展为多维变量成分，可有效避免卷积盲源分离过程中的排序模糊性问题。(Independent vector analysis (IVA), a multivariate extension of independent component analysis, tackles the convolutedly mixed blind source separation (BSS) problem in a way to avoid the permutation problem by employing a multivariate source prior of the short-time Fourier transform (STFT) components. )

说明：  构建三层次的BP神经网络，通过多项指标预测含水层涌水能力，(Prediction of aquifer water inflow capacity based on BP neural network)
