As one of the ideas:
v1 = [1, 2, 3, 4]
v2 = [5, 6, 7, 8, 9, 10]
lv1 = length(v1)
lv2 = length(v2)
v = zeros(1,max(lv1,lv2)*2)
v(1:2:lv1*2) = v1
v(2:2:lv2*2) = v2

This would leave 0s untouched in places where one vector was shorter than the other. Which might be fine or might not be.
Note that in general it would be better to supply class(v1) as the final argument of zeros(), to handle the situation where the vectors were (e.g.) uint8

V = reshape([V1;V2], 1, []);

That only works for vectors with the same dimensions. How do you account for ones without?

Then the two vectors would not be "1xN dimensions" and it would be a different Question -- one would immediately attract questions about what it meant to interweave if the two vectors were not the same size.
