7.2: Introduction to Gauss Jordan Elimination
( \newcommand{\kernel}{\mathrm{null}\,}\)
The following elementary row operations
- Interchange two rows of a matrix
- Multiply the elements of a row by a nonzero constant
- Add a multiple of the elements of one row to the corresponding elements of another
Consider the element a2,1 in the following A Matrix.
A=[112025|30690]
Describe an elementary row operation that could be used to make element a(2,1) zero?
What is the new matrix given the above row operation.
Modify the contents of this cell and put your answer to the above question here.
A=[110??|30??]
The following function is a basic implementation of the Gauss-Jorden algorithm to an (m,m+1) augmented matrix:
