Thread: Question about matrix

1. Question about matrix

if i have some matrix $A$ which does have $m$ rows by $n$ columns. How is that matrix represented in space?

2. $
im(A)=span(\vec{v}_1,\cdots,\vec{v}_n)
$

3. What actually are these vectors. I can imagine them in 2d, 3d space and maybe in 4,5,6d space. What they represent. I want to try to visualize matrix in space.
