说明：  Modify the Matlab Gauss Elimination routine given in lectures so that it (a) performs implicit complete pivoting, and (b) handles m right hand sides at once by performing an LU decomposition of the matrix A first and then doing forward substitution and back substitution (hence not modifying the right hand side as the elimination is perfomed). Test your program and then run it on the system AX = B(Modify the Matlab Gauss Elimination routine given in lectures so that it (a) performs implicit complete pivoting, and (b) handles m right hand sides at once by performing an LU decomposition of the matrix A first and then doing forward substitution and back substitution ( hence not modifying the right hand side as the elimination is perfomed).

说明：  信噪比估计代码，附有IEEE文献一篇，在AWGN下进行了MCRB的相关仿真(A Comparison of SNR Estimation Techniques for the AWGN Channel)

混沌理论教材，从不同的角度处理数据，利用最小二乘法消除线性趋势，结果好于差分方法。(Chaos theory textbooks, processing data a different angle, eliminating the use of least squares linear trend, the result is better than the differential method.)
