The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

算术编码是把一个信源表示为实轴上0和1之间的一个区间,信源集合中的每一个元素都用来缩短这个区间。 算术编码的过程如下: (1)设定编码区间的高段为h,编码区间的长度为g,EndC为编码字符分配的高段,StartC 为字符分配区间的低端。 (2)根据有限的信源估算出各元素的概率。 (3)杜宇编码的元素A1,根据(2)估算的概率和区间,计算出该元素编码后的新的l,和h。

Problem B:Longest Ordered Subsequence A numeric sequence of ai is ordered if a1 < a2 < ... < aN. Let the subsequence of the given numeric sequence (a1, a2, ..., aN) be any sequence (ai1, ai2, ..., aiK), where 1 <= i1 < i2 < ... < iK <= N. For example, sequence (1, 7, 3, 5, 9, 4, 8) has ordered subsequences, e. g., (1, 7), (3, 4, 8) and many others. All longest ordered subsequences are of length 4, e. g., (1, 3, 5, 8).
