基于ＭＡＴＬＡＢ的小波分析应用：运用小波的时域、频域特征对摩托车发动机故障诊断和齿轮点蚀故障诊断(Wavelet analysis of MATLAB-based applications: the use of wavelets in time domain, frequency domain characteristics of motorcycles engine fault diagnosis and fault diagnosis of gear pitting)

此例程为配套书籍的第六章例题6-5的相对应代码，功能为计算非平稳随机信号的WVD时频谱，编程环境为matlab。(This routine matching books Chapter Example 6-5 corresponding to the code for the calculation of the non-stationary random signal WVD spectrum programming environment for matlab.)

Function direct I Filter Call: [Y,Zf]=FDI(B,A,X,Zi) Parameters A(N), B(M), X(L)and Y(L) as in FILTER. Input Parameters: Zi(max(N,M)-1,2): Conditions iniciales. Zi(:,1): from zeros. Zi(:,2): from polos. Output Parameters: Zf(max(N,M)-1,2): final conditions. Zf(:,1): from zeros. Zf(:,2): from polos.

GSCALE Scales the intensity of the input image. G = GSCALE(F, full8 ) scales the intensities of F to the full 8-bit intensity range [0, 255]. This is the default if there is only one input argument. G = GSCALE(F, full16 ) scales the intensities of F to the full 16-bit intensity range [0, 65535]. G = GSCALE(F, minmax , LOW, HIGH) scales the intensities of F to the range [LOW, HIGH]. These values must be provided, and they must be in the range [0, 1], independently of the class of the input. GSCALE performs any necessary scaling. If the input is of class double, and its values are not in the range [0, 1], then GSCALE scales it to this range before processing. The class of the output is the same as the class of the input.

一个基于内容的图像检索系统，对搞图像检索的应该会有所帮助！！！(A content-based image retrieval system, engage in retrieval should help! ! !)

This program just tracks all red color objects and draws a bounding box around them

MATLAB编写利用P-Q分解法的潮流计算程序，程序中利用基于稀疏技术的因子表法进行迭代求解，以降低存储量，提高运算速度。本程序只适用于简单系统，如IEEE5节点系统。对于复杂系统，由于PV节点电压越限等问题尚未考虑，得到的潮流结果可能有误！(MATLAB flow calculation program written using PQ decomposition method, program utilization based on sparse iterative solver technology factor table method to reduce the storage capacity, improve processing speed. This procedure applies only to simple systems, such as IEEE5 node system. For complex systems, PV node voltage due to the more limited issues not yet considered, the trend of the results obtained might be wrong!)

Program generate a random binary sequence, introduce ISI and show the diagrams. Next filter minimalized ISI and generate the graph.
