"notice": Because W is the N-order matrix (n is the total number of pixels of the image, that is, the length of the Pi), the computational amount is too large for it to be directly SVD. So we can start with the W transpose SVD, because P is nxm matrix, M is the number of vectors (that is, training and size), mBoth sides simultaneously left multiply P:– Standard orthogonal matrix for ppt:– We are using SVD to find the PTP standard orthogonal matrix, namely VP,VP-1=VPT.

Io_service class you should have found that most of the code written with Boost.asio uses several Ios_service instances. Ios_service is the most important class in this library, it is responsible for dealing with the operating system, waiting for the end of all asynchronous operations, and then invoking the completion handler for each asynchronous operation. If you choose to create your app in a synchronized way, you don't have to think about what I'm going to show you in this section. You can u

Exception handling vs error CodeBoost.asio allows for both exception handling or error code, and all async functions have overloads that throw errors and return error codes in two ways. When a function throws an error, it often throws a boost::system::system_error error. using Boost::asio;Ip::tcp::endpoint EP;Ip::tcp::socket sock (service);Sock.connect (EP); Line 1Boost::system::error_code err;Sock.connect
