Question: how to animate a vector

i interpolate data and result in 96 equations

and then solve them and saved their roots into Vector roo, each of roo has 3 roots

and would like to animate first root of 96 equations, second root of 96 equations to see how roots move 

however meet difficulty when animate, how to animate this

moreover, is it possible to slow down the anime when playing it

> roo; Vector(4, {(1) = ` 1 .. 99 `*Vector[column], (2) = `Data Type: `*anything, (3) = `Storage: `*rectangular, (4) = `Order: `*Fortran_order})>

roo[1][1];                               

0.

> roo[1][2];                         

3.855730820

> roo[1][3];                         

2.050519180

> roo[2][1];                         

4.037136874
animate( plot, roo[A][1]], A=1..96);
