Row, Column and Null Space of a Matrix - Linear Algebra

The video gives the definition of and explains the difference between row, column and null space of a matrix, finding the basis using row echelon form, and row and column vectors. You will understand if row space is the same as null space, what is the null space is 0 and what is meant by them.
