For more information about the matrix account, you can go to the "Yunlue pro" public account "Charge 618!" Three matrix building skills that must be mastered to make the brand more blooming and more competitive! 》 View After seeing this question, I couldn’t help but want to answer it! Let’s break down the problem first: First,. How to intuitively understand matrices and linear algebra? I want to intuitively understand the definition, operation rules and properties of matrices, such as eigenvectors and so on. There is a widely circulated "Comprehension Matrix" on the Internet. The third article "Comprehension Matrix (1)". I really appreciate the idea of such a tutorial. According to the definition of inverse matrix. Since the block matrix satisfies the matrix addition and multiplication operations. Therefore, its inverse matrix is assumed to be the same in blocks. Perform matrix multiplication with the original matrix to make the obtained matrix the identity matrix. However, for most chunks, this operation does not work.

Abc=a (bc) But matrix operations do not have the commutative law of multiplication, and in most cases, ab \ne ba.
