To do data structure in the course of information, mainly to look at the inverse matrix of knowledge. The Gaussian-approximate (Gauss-jordan) elimination method of the chosen principal element is used in many places, for example, to find the inverse matrix of a matrix, to solve a linear equation group (one of the steps of the LM algorithm), and so on. Its speed is not the fastest, but it is very stable (from the definition of the Internet: A calculati

Many people say that Jordan has become a god of honor and six champions. Honors and champions are collective. So he has nothing to do with it. But as a matter of fact, Russell has 11 and his fingers are not enough. With regard to records and data, most of the records and data kingdom are maintained by John R. The reason why Jordan is terrible is that he has gathered a strong collective honor and a strong re
The standard form theorem of Jordan is the basic theorem in linear algebra. It seems redundant to write a long article for it: there are too many handouts in this field! What new ideas can be written for an old theorem?
There are two reasons. The first reason is that when I spoke to students about this theorem, I suddenly found that I didn't know how to inspire students. Although I know many proofs of Jordan's standard form theorem, I think it's a bit

First of all obviously there is a formula (20) of the series equation, through a simple calculation can be obtained formula (21), this formula shows that the power 0 matrix decomposition of the number of cyclic subspace and the number of times are determined, it can be said that this decomposition is unique.\[\text

There were already signs that he had a good deal of talent. harvest Smith, a classmate and close friend who in those days played basketball with him practically every day, thought he was the best player on their ninth-grade team-he was small, but he was every quick. "You 'd see him get a shot off, and you 'd wonder how he did it, because he wasn' t that bit," Smith said, "but it was the quickness. the only question was how big he was going to be-and how far up he wowould take his skill level."
