Hi all

Assume that we have following vectors:

> V1 := [1/9, -5/9, 7/9, 1/9, -5/9, 7/9, 1/9, -5/9, 7/9];

> V2:=t*V1;

and we want to compute the integral of V2, namely:

> Int(seq(V2[i],i=1..9),t=0..1);

>

[ 5 t 7 t 5 t 7 t 5 t 7 t]

V2 := [t/9, - ---, ---, t/9, - ---, ---, t/9, - ---, ---]

[ 9 9 9 9 9 9 ]

Error, (in print/Int) invalid input: IntegrationTools:-GetOptions expects its 1st argument, v, to be of type Integral, but received Int(1/9*t,-5/9*t,7/9*t,1/9*t,-5/9*t,7/9*t,1/9*t,-5/9*t,7/9*t,t = 0 .. 1)

how we integrate from V2? why answer is wrong in my code?

thanks a lot
