Question: animate a set of vectors

Hello all, 

How to animate a set of vectors?

for example, 

q:=Matrix(3,10,(i,j)->i^2+j+2*i); # some matrix which holds the 3x1 vectors. 


animate(arrow,[q(..,i)],i = 1..10);

I get an error 

Error, unsupported type of index, i

In real use, the input to 'arrow' function will be a vector valued function so the 'animate' command will show the resulting vectors.
