Ex0101.m 实现matlab下的数据存取(Ex0101.m to achieve data access under matlab)

function [a,b] = pade(x,p,q) PADE Model a signal using the Pade approximation method ---- Usage: [a,b] = pade(x,p,q) The input sequence x is modeled as the unit sample response of a filter having a system function of the form H(z) = B(z)/A(z) The polynomials B(z) and A(z) are formed from the vectors b=[b(0), b(1), ... b(q)] a=[1 , a(1), ... a(p)] The input q defines the number of zeros in the model and p defines the number of poles.

核函数主成分分析，用于数据的特征提取，对于训练样本的降维有较好的效果(Kernel principal component analysis, feature extraction for data, which can effectively reduce the dimension of training samples, the better)

小电流接地系统发生接地故障时，利用prony算法提取暂态特征分量并利用相关分析法实现选线取得很好的效果，有效的排除了干扰信号的影响，结论明显、准确性高。(When the small current grounding system occurs ground fault , we use prony algorithm to extract the transient characteristics of the component and line selection by using correlation analysis. The simulation present that the algorithm effectively eliminate the influence of interfering signal. The result has a good effect and high accuracy obviously.)

GDDEMO runs a little demonstration of gradient descent in Matlab. Launch Matlab, and type gddemo to get started.
