I must be missing something simple, but I sometimes find myself needing to
concatinate arrays as follows:

x = FINDGEN(10)
y = FINDGEN(4,20)
z = [x, y(1,*)]

This won't work because IDL sees y(1,*) as a 2-d array, and x is 1-d.
Is there an easy way to concatenate two "vectors" without looping through
the y-array and extracting the approriate elements like this:

temp = FLTARR(N_ELEMENTS(y))
for i=0,N_ELEMENTS(y)-1 do temp(i) = y(1,i)
z = [x,temp]

Thanks
