Question

Given a vector v = [1 2 3 4 5 6] how do I turn it into:

v = 
    v(:,:,1) =  1
    v(:,:,2) =  2
    v(:,:,3) =  3
    v(:,:,4) =  4
    v(:,:,5) =  5
    v(:,:,6) =  6

i.e., transpose between the second (row) and third dimension?

Answer 1

The answer is to use the permute command:

permute([1 2 3 4 5 6], [3 1 2])

It accepts non-existing dimensions: the second argument specifies swapping the first existing dimension with the third existing dimension (none), which creates a ‘singleton’ first dimension in the result.
