Special Insertion of Multiple Vectors into One Vector

[hriek]

I'm thinking I need for loops to insert vectors P, M and V into Q as follows:

P₀ into Q₀

P₁ into Q₃

P₂ into Q₆

P₃ into Q₉

M₀ into Q₁

M₁ into Q₄

M₂ into Q₇

M₃ into Q₁₀

V₀ into Q₂

V₁ into Q₅

V₂ into Q₈

V₃ into Q₁₁

I need help with the programming and sequencing.

How about this?

No programming needed.

If you want to do it programmatically, you could go this way:

What about for an arbitrary sizes of vectors P, M, V? (these vectors will always be the same size)

In both examples, you can simply change the definition of k from "0...3" to "0...last(P)"
