Recently began preparing for a lab study while documenting some of the programming trivia points encountered. Today when testing the SVD decomposition of matrices, we need to define the size of the rows and columns of the matrix, and I used to define these two variables with a macro definition, and when I run, I start thinking about what the difference between the macro definition and the constant is.Refer to some other people's statements, I do a sma
In fact, although a programmer, there is a kind of literary heart, reading humanities books than the joy of reading technology.In the past, originally like to write in diary, including the development of learning strategy plan, record life trivia, etc. later like in QQ space to write things, now QQ log there is a bunch of young pretentious masterpiece, occasionally read or marvel at the time of the Literary foundation, now long forgotten those flowery

I learned a lot through this vote.a long time agoI have hardly ever written a personal touch in csdn, because it feels like an open platform and does not want to go as a journal to keep track of your trivia, as to why this article will be written later.So this article is not just a summary of the vote, it also contains a long time ago.
