$, $\sigma$ is a matrix of $m \times n$, except that the elements on the main diagonal are all 0, each element on the main diagonal is called a singular value, and V is a matrix of $n \times n$. Both U and V are unitary matrices, that is, satisfying $u^tu=i, v^tv=i$. The definition of SVD can be seen very visually:So how do we find the SVD decomposition of $u, \sigma, v$ these three matrices?If we multiply the transpose of a and a matrix, we get a square $a^

Hello.
It is a great honor to be here in such a magical place as Shanghai and join a harmonious company to work with you for so long. However, I have to be ashamed to say that I am not a hard-working person. My goal in Shanghai is not a career, but a silly love. And I do not think it is love.

There are two ways to start Multithreading: (All under the main thread)1. Use the same thread object to start multiple threads2. Use multiple thread objects to start multiple threadsWhat is the difference between these two ways? First put the code to illustrate:This is the same instance r that uses the thread object myrunnable to start up two threadsNewnew thread (R, "Thread-a"new thread (R, "Thread-b"); Ta.start (); Tb.start (); This is two different instances of using thread object Myrunna

In the introduction and application of automated testing, we understand some basic principles:
-If you select a proper tool, the most popular tool may not be suitable for you. The most suitable tool is the best. For example, robot is not necessarily the best, but its multi-machine interaction and collaboration capabilities are not available in other tools.
-Different test tools can be selected based on different features of the client, web, and server, such as web links, fast UI changes, and
