小波包4级分解及特征向量空间的建立，希望对大家有用(4 wavelet packet decomposition and feature vector space for the establishment, in the hope that useful to everybody)

说明：  FIR数字滤波器的设计方法主要是建立在对理想滤波器频率特性作某种近似的基础上的。这些近似方法有窗函数法、频率抽样法、最佳一致逼近法。在这里只讨论窗函数法。程序中也是采用了这种方法。(FIR digital filter design method is mainly based on the frequency characteristics of the ideal filter for some kind of approximation on the basis of. These approximate methods are a window function method, frequency sampling method, the best uniform approximation method. Here only to discuss the window function method. Procedure is also adopted this approach.)

说明：  差分维数计算源代码，大家一定用得到！！！(Differential dimension calculation source code, we must use to get! ! !)

3524工作原理,似乎是很牛的解释，里面有图，解释的很清楚~(how does the 3524 play~)

格式 [sqnr,a_quan,code]=u_pcm(a,n) 输入样值序列a 、量化电平数目n, 程序计算量化间隔、进行均匀量化、进行编码、计算量化信噪比， 返回量化信噪比squn、编码前的量化序列a_quan、编码后的码序列code。 (Format [sqnr, a_quan, code] = u_pcm (a, n) input sample value sequence a, the number of quantization levels n, the calculation procedures to quantify interval, the uniform quantization, coding, computing quantization noise ratio, return quantization noise ratio squn, to quantify the pre-coding sequence a_quan, coding sequences after the code.)

说明：  用于计算高频下的金属介电常数，主用侧重应用于有限元分析仿真中金属材料的物理属性。(The metal used to calculate the high frequency dielectric constant, the main emphasis used with finite element analysis simulation of the physical properties of metal materials.)

牛顿迭代法求无约束一维极值问题的速度相当快，而且还有一个好处就是能高度逼近最优值。(Newton iteration method for one-dimensional unconstrained extremum problem very fast, but there is a benefit that can be highly close to the optimal value.)
