Variable types are usually not written

Operators are consistent with language, and or not

Copy Language A<-b

Content Interchange A<->b

1. Theory of the solution of the linear equation group

For a linear equation group

Identification of the solution:

Step1: Elementary Line transformation to row-stepped matrix, Gaussian elimination element

Algorithm:

Step2 Solution:

Algorithm:

Step3: sufficient and necessary conditions for the solution of a linear equation group

        

STEP4: Number of solutions

1. The unique solution dimension is equal to the number of unknowns, whereas the infinitely multiple solution

2. Homogeneous linear unique solution: 0 vector, Reverse: from the unknown amount () to solve the general solution, the return

3. Non-homogeneous unique solution: direct return, corresponding to the second general solution + Special Solution
