| Abstract: | Matrix,which is a very important and widely used part in mathematics,is a main subject and an important tool in researching algebra. It is used widely in mathematics, physics, economics, and other fields. A knowledge of Matrix is the basic of solving linear algebra problems. Inverting matrix plays an important role in the matrix theory and plays the role of the Inverse number in rational numbers, so judging whether the matrix has an inverting matrix is very important in Matrix operations . |
