Flashcards
What is the second elementary row operation?
Multiplying by a non-zero scalar.
What’s Gauss elimination?
The process of systematically using EROs to introduce zeroes into the lower triangle.
What’s Gauss-Jordan elimination?
Like Gauss elimination except you also make the upper triangle zeroes.
When is it necessary to use the first ERO (swapping the rows)?
When it’s not possible to make a zero using the other rows.
