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 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.

本書第二版和第三版之間的變化非常大其中最值得注意的是C++已經通過了國際標 準化這不但為語言增加了新的特性比如異常處理運行時刻類型識別RTTI 名字空 間內置布爾數據類型新的強制轉換方式而且還大量修改并擴展了現有的特性比如模 板template 支持面向對象object-oriented 和基于對象object-based 程序設計所需 要的類class 機制嵌套類型以及重載函數的解析機制也許更重要的是一個覆蓋面非 常廣闊的庫現在成了標準C++的一部分其中包括以前稱為STL 標準模板庫的內容新 的string 類型一組順序和關聯容器類型比如vector list map 和set 以及在這些類型 上進行操作的一組可擴展的泛型算法generic algorithm 都是這個新標準庫的特性本書 不但包括了許多新的資料而且還闡述了怎樣在C++中進行程序設計的新的思考方法簡而 言之實際上不但C++已經被重新創造本書第三版也是如此

平均因子分解法，適用于正定矩陣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.
