how to convert between bases

In the learning Python3 process found that Metaclass's usefulness is more extensive, more can view PEP 3115. In the learning process need to do some serialization operations (such as CSV conversion), access to data discovery, the use of the Meta

  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

1. Vectors and their base transformations1.1 Vector inner product(1) The inner product of a vector of two dimensions is defined as follows: The inner product operation maps two vectors to a real number.(2) geometrical meaning of inner

Today, I was suddenly asked, What is the matrix used? What is the significance of its feature root. The answer is far-fetched. Later, I searched for a lot of things on the internet and thought it was good to share them. The Matrix is a description

Not long ago, for some ulterior motives, chensh wanted to act as a teacher and teach others linear algebra. As a result, I was held down and discussed with him several times about the virtual nature of linear algebra. Obviously, it is difficult for

  Then we understand the matrix. In the previous article, "the matrix is the description of motion." So far, it seems that everyone has no opinions yet. But I believe that sooner or later there will be a netizen from the mathematics department.
