    function A = set_reorder(A, B, idx, dim)
%SET_REORDER Assigns B to A with one of the dimensions of A indexed.
%
%   A = SET_REORDER(A, B, IDX, DIM)
%
%   Returns A after doing A(:, ..., :, IDX, :, ..., :) = B
%   where DIM determines in which dimension to place the IDX.
%
%   See also GET_REORDER.
