Coding for image retri

matlab 代码，实现softmax的多分类(Matlab code, the realization of softmax classification )

是本科毕设的题目，用平面波展开法计算二维声子晶体带隙,有较好的参考价值。( The title of the commercial is undergraduate course you Computation Method D phononic bandgap plane wave, There are good reference value.)

说明：  对于Rossler方程组这样的非线形微分方程组，不可能求得其解析解，利用MATLAB可以用数值解法进行模拟。(Rossler equations for the non-linear differential equations, it is impossible to seek its analytic solution, using MATLAB method can be used for numerical simulation.)

m序列产生m序列产生m序列产生m序列产生m序列产生m序列产生(m-sequence generator m sequence generation m-sequence generator m-sequence generator m sequence generation m-sequence generator)

波达方向（DOA） 估计的基本问题就是确定同时处在空间某一区 域多个感兴趣的信号的空间位置(即多个信号到达阵列参考阵元的方 向角)。最早的也是最经典的超分辨率(DOA)估计算法是著名的多信号 分类（Multiple Signal Classification） 法,简称 MUSIC 算法,它是 一类经典的基于特征结构分析的空间谱估计方法。该算法利用了信号 子空间和噪声子空间的正交性,构造空间谱函数,通过谱峰搜索,检测 信号的 DOA。(The basic problem of DOA estimation is to determine the simultaneous location in a certain region of space. Spatial position of multiple interested signals in the domain (i.e. the direction of multiple signals reaching the array reference elements) Directional angle). The earliest and most classical super-resolution (DOA) estimation algorithm is the well-known multi-signal.Multiple Signal Classification, referred to as MUSIC algorithm, is A classical spatial spectrum estimation method based on eigenstructure analysis. The algorithm utilizes signals. The orthogonality of subspace and noise subspace, the construction of spatial spectral function, through peak search, detection DOA of signal.)

标准NOISEX-92噪声库，对于声音信号分析的人有用。(Standard noise NOISEX-92 library, the human voice signal analysis for useful.)
