平均因子分解法应用于正定矩阵
平均因子分解法,适用于正定矩阵First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies:
(1) U U = X
(2) U is upper triangular (that is, it has all zeros below the diagonal).
It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition. -Average factor decomposition method applied to positive definite matrix First, let s recall the definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X = UU, where U is the square root matrix of X, and satisfies: (1) UU = X (2) U is upper triangular (that is, it has all zeros below the diagonal).

superpiexl 段
superpiexl 是一种分割方法和理念,将图像分割成一个个类似大pixel的块儿,艾玛,我的表述怎么这么不给力,总之,它是图像预处理过程。这里上传的这个code,是superpiexl的实现,可以直接使用,观察图像分割的结果,enjoy it!

json 完美解析代码
JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式。它基于JavaScript(Standard ECMA-262 3rd Edition - December 1999)的一个子集。 JSON采用完全独立于语言的文本格式,但是也使用了类似于C语言家族的习惯(包括C, C++, C#, Java, JavaScript, Perl, Python等)。这些特性使JSON成为理想的数据交换语言。易于人阅读和编写,同时也易于机器解析和生成。
利用这个库,可以和你的c/c++应用无缝集成
