skyline method to inverse K matrix in [K]{X}={F}

基于Matlab对约瑟夫森结（Josephson Junction）RCSJ模型的交直流I-V特性及非线性混沌现象进行数值模拟。通过计算机数值模拟得到该模型的非线性微分方程数值解，研究了RCSJ模型中各参量对约瑟夫森结的影响，进而简要分析其I-V特性和非线性混沌现象的产生机理，绘制出约瑟夫森结的交直流I-V特性曲线、非线性微分方程的相图及因其高度非线性而引起的通过倍周期分岔和阵发性原理进入混沌状态的分岔图。还给出庞加莱截面及功率谱。(Matlab based on the Josephson junction (Josephson Junction) RCSJ model AC and DC IV characteristics and non-linear numerical simulation of chaotic phenomena. Through computer simulation model by the numerical solution of nonlinear differential equations to study the RCSJ model parameters on the impact of Josephson junction, and a brief analysis of the IV characteristics and the emergence of the phenomenon of non-linear chaotic mechanism, drawn Josephson junction IV characteristic curve of AC-DC, non-linear differential equations and the phase diagram because of its highly nonlinear arising through period-doubling bifurcation and chaotic state of paroxysmal principle of access to the bifurcation diagram. Poincare cross-section and was also given power spectrum.)

一个系统辨识例程，用递推贝叶斯方法辨识一个系统的四个参数，程序有注释和说明，系统系数在程序中给出。(Of a system identification routine, using recursive Bayesian identification of a system of four parameters, procedure notes and instructions, the system coefficients is given in the program.)

本程序为一段信号相关分析，定义了一个相关函数，用的时候直接调用即可。由于上传匆忙，有地方未修改，下载者请将pCorr这个程序段中Rxy(i)=Rxy(i)/i这段删掉，否则会出错(This program is a signal correlation analysis, the definition of a correlation function, when used in direct calls to)
