对声音服务进行AAC音频解码，对数据业务进行解压缩和数据归类(AAC decoding for audio services ，Data sorting and decompression for data services )

一种分析混沌信号的多重分形谱的简单程序，尤其分析网络流量中尤为有效

mat lab code for elim elim E*A = R factorization. E = elim(A) returns the elimination matrix E that gives the reduced row echelon form E*A = R. If A is square and invertible, then E = inv(A). [E, R] = elim(A) returns the elimination matrix E and the reduced row echelon form R.
