3. Example `[[3,-1,-1],[2,-2,1]]`
Find Column Space ...
`[[3,-1,-1],[2,-2,1]]`Solution:Now, reduce the matrix to row echelon form `R_2 larr R_2-2/3xx R_1` | = | | `3` | `-1` | `-1` | | | `0` | `-4/3` | `5/3` | |

The rank of a matrix is the number of non all-zeros rows `:. Rank = 2` Column Space : The matrix has 2 pivots and Pivots are in the columns 1 and 2. We know that these columns in the original matrix define the column space of the matrix. `:.` The Column Space is `[[3],[2]],[[-1],[-2]]`
