Filling a vector at some places

[<Andre.Mery@aventis.com>]

Hi,

 

I am stuck by the following problem.

 

I have a vector with 36 positions, all set to 0:

vec1 =  0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Now, after some other calculations, I get a the vector:

vec2 = 18  1  5  2

And so, I want to transform the vec1 to a vec3:

 vec3 =  1 1 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

where 1s appear at the places indicated by vec2 (places # 1, 2, 5 and 18)

I can't find a simple way to do so. Can anyone enlighten me ?
