    Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution % % compute the forward/backward Campbell/specgtrogram % % INPUT: % y (n x 2) each column is measured from a different sensor % /////// % __ % |s1| y(:,1) % |__| % __ % / \ ________|/ % | | | s2 |/ y(:,2) % \____/ --------|/ % % Fs Sampling frequnecy % % OUTPUT: % B spectrogram/Campbel diagram % x x-axis coordinate vector (time or Speed) % y y-axis coordinate vector (frequency [Hz])

  • Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree

    Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coefficients are used for wavelet transform operation wahich is saved in wavcoeff.mat.

    本书第二版和第三版之间的变化非常大其中最值得注意的是C++已经通过了国际标 准化这不但为语言增加了新的特性比如异常处理运行时刻类型识别RTTI 名字空 间内置布尔数据类型新的强制转换方式而且还大量修改并扩展了现有的特性比如模 板template 支持面向对象object-oriented 和基于对象object-based 程序设计所需 要的类class 机制嵌套类型以及重载函数的解析机制也许更重要的是一个覆盖面非 常广阔的库现在成了标准C++的一部分其中包括以前称为STL 标准模板库的内容新 的string 类型一组顺序和关联容器类型比如vector list map 和set 以及在这些类型 上进行操作的一组可扩展的泛型算法generic algorithm 都是这个新标准库的特性本书 不但包括了许多新的资料而且还阐述了怎样在C++中进行程序设计的新的思考方法简而 言之实际上不但C++已经被重新创造本书第三版也是如此

  • 平均因子分解法

    平均因子分解法,适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition.
