Interleave and Deinterleave a vector into two new vectors

Question

Interleaver: Assume we have vector X= randi(1,N) I would like to split the contents of X into two new vectors X1and <

Answer 1

Just to add another option, you could use the deal function and some precomputed indices. This is basically the same as the answer from Peter M, but collecting the assignments into single lines:

X = randi(10, [1 20]);  % Sample data
ind1 = 1:2:numel(X);    % Indices for x1
ind2 = 2:2:numel(X);    % Indices for x2

[x1, x2] = deal(X(ind1), X(ind2));  % Unweave (i.e. deinterleave)

[X(ind1), X(ind2)] = deal(x1, x2);  % Interleave
