用镜像矩阵求出矩阵的QR分解（正交三角分解），并求解线性方程组，该方法不必选主元，但其计算过程非常稳定。也可用于求矩阵的广义逆和求解线性最小二乘问题。子过程QRDCMP用镜像矩阵求m*n矩阵A的QR分解，A=Q^TR,其中Q是m*m正交矩阵，R为m*n上三角矩阵；子过程QRBKSB用矩阵的QR分解求解线性方程组Ax=b，其中A为n阶非奇异方阵。(Matrix obtained with the mirror matrix QR decomposition (orthogonal triangular decomposition), and solving linear equations, the method does not have to choose the main element, but its calculation process is very stable. Can also be used to find the generalized inverse matrix and solving linear least squares problems. Sub-process of the mirror matrix QRDCMP m* n matrix A QR decomposition, A = Q ^ TR, wherein Q is a m* m orthogonal matrix, R is m* n upper triangular matrix subprocess QRBKSB a QR decomposition to solve the matrix linear equations Ax = b, where A is non-singular square matrix of order n.)

一个简单的C++程序：输入两个整数，通过调用函数求两个数中的较大值(A simple C++ program: the input of two integers, by calling the number of two of the larger values)

The sample code depicts three different use cases of AVAssetResourceLoaderDelegate (for Identity encryption use case scenarios) for HLS (HTTP Live streaming): - Redirect handler (redirection for the HTTP live streaming media files) - Fetching Encryption keys for the HTTP live streaming media (segments) - Custom play list generation (index file) for the HTTP live streaming. 示例代码描述了HLS（HTTP实时流）的AvassetResourceLoaderDelegate（用于标识加密用例方案）的三个不同用例：—重定向处理程序（HTTP实时流媒体文件的重定向）—获取HTTP实时流媒体（段）的加密密钥—自定义播放列表生成（索引文件）for HTTP直播流。(The sample code depicts three different use cases of AVAssetResourceLoaderDelegate (for Identity encryption use case scenarios) for HLS (HTTP Live streaming): - Redirect handler (redirection for the HTTP live streaming media files) - Fetching Encryption keys for the HTTP live streaming media (segments) - Custom play list generation (index file) for the HTTP live streaming.)
