actually, there was no transformation. you took the first two scalars
from col_vec and assigned them to the first two positions of row_vec.
you could have done the same for a multidimensional matrix. It didn't
transform orientation, it retained orientation on the original vector,
and assigned element values as you asked.

octave:17> a = 1:4
a =

   1   2   3   4

octave:18> b = a'
b =

   1
   2
   3
   4

octave:19> c = magic(4)
c =

   16    2    3   13
    5   11   10    8
    9    7    6   12
    4   14   15    1

octave:20> a(1:4)=c(7:10)
a =

    7   14    3   10

octave:21> b(1:4)=c(7:10)
b =

Matlab / Octave have always supported one dimensional addressing of
one and multidimensional arrays as it corresponds to how they're
stored in memory. No warnings because what you did was within the
realms of accepted array behavior since Matlab was first written.
