Hello Everyone,

I have been given 4 vectors [1 2 3 0], [2 3 0 4], [5 0 6 7], [8 5 9 11] and been asked to find the dimension of the subspace spanned by the vectors listed above.

I have gone ahead and put these vectors into a matrix

1 2 3 0

2 3 0 4

5 0 6 7

8 5 9 11

I have proceeded to reduce these to row echelon form but am unsure of what I should do next?

any insight or help would be greatly appreciated.

Thanks
