这个代码使图像压缩的离散余弦变换，量化，反量化和反离散余弦变换。定量后，我们计算的数“0”表示测量矩阵的结果。而且，我们计算峰值信噪比显示性能。M文件和256×256

该程序功能为对所输入的振动信号进行希尔伯特黄变换，得到其边际谱(The program features the vibration input signal Hilbert Huang transform and its marginal spectrum of)

实现了对10个数字音的识别程序已调制信号计算其普相关密度，包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，使用拉亚普诺夫指数的公式，gmcalab 快速广义的形态分量分析，关于神经网络控制。

This derivation of the normalised least mean square algorithm is based on Farhang- Boroujeny 1999, pp.172-175, and Diniz 1997, pp 150-3. To derive the NLMS algorithm we consider the standard LMS recursion, for which we select a variable step size parameter, μ(n). This parameter is selected so that the error value , e+(n), will be

分别用Ansys和Matlab建立的混凝土骨料随机投放模型，建立二维，三维数值混凝土模型，对分析混凝土的破坏机理具有重要参考价值。(Concrete aggregates were used Ansys and Matlab established random delivery model, a two-dimensional, three-dimensional numerical model of concrete, concrete analysis of the failure mechanism has important reference value.)
