How to Find Out Rank of Matrix

A common approach to finding the rank of a matrix is to reduce it to a simpler form, generally row echelon form, by elementary row operations. Row operations do not change the row space (hence do not change the row rank), and, being invertible, map the column space to an isomorphic space (hence do not change the column rank).
This video will show you how to find rank.

why do we find the number of independent columns/rows? What is its significance?

[vitalivardanidze]

Great video, well explained, really helped

[rockyjoe]

Nice video but isn't the column[1, 2] a multiple of [2, 4] since it can be expressed as 0.5[2, 4]? Correct me if something is wrong please, thanks!
