Hello,
I'm using EViews 7.
I need to create a vector from 3 vectors of different size.
How can I do that?
Thanks!
Danny

A matrix is a rectangle. Conceptually, how do you envisage making one from 3 different sized vectors?

Gareth,
vec1 is 1x20, vec2 is 1x32 and vec3 is 1x 40
I want to stack vec1, vec2 and vec3 one over another in order to have one big vector.
Can I do that?
Thanks!

There's a @vcat function to perform vertical concatenation

Gareth,
This a function seems to be available only on EViews 8.
Thanks anyway!

Ah, true.
Create a vector of the correct size, then use the matplace function to insert your smaller vectors.
