Instead of the latter, A = REBIN(TRANSPOSE(V), 100, 25) may be
slightly more efficient.

But you can also use a matrix multiplication: A = MAKE_ARRAY(100,
VALUE=1) # V

The question whether the REBIN or the matrix multiplication is faster
is not easy to answer. It will depend on number of elements and on the
hardware and software configuration you are using.
