We can solve our system linear equations by transforming the system linear equation into the matrix form. We already learn to solve it using REF and RREF. Now we will learn how to solve it using the inverse matrix and Factorization Matrix.
Solving a System of Linear Equation using the Inverse
Video below is to make you understand more how to solving the linear equation using Inverse Matrix.
And here the video to solve using Factorization.
1. LU decomposition
2. Doolittle Factorization
3. Crout Factorization.
