Suberb: Both Gaussian elimination and presentation. Thanks.

*Superb

Is there anything to say about the relationship between the column space you start with and the column space post Gaussian Elimination?

[@MathTheBeautiful]

Excellent question! Well, they have the same dimension. But a more detailed relationship is given by Strang's CR decomposition, see czcams.com/video/NJKe2MQxa9k/video.html
