Randomly assign elements of one vector into different vectors?

Hello I have the next vector:
v= [1 2 2 3 1 3 2 1 3 2 1 3 2 1 3 1 2 3 1 3]
And I need to assign randomly 4 elements of this vector in v1 other 3 elements in v2 other 5 elements in v3, 5 in v4 and 3 in v5 but without replacement, so each time these elements are assign to the first vector can not be assing to second and so on.
Is possible to do this with the randsample command?

When you say "in v1" do you really mean assign to v1? In other words, get the specified number of elements from v, and replace some elements in an existing v1 with the values from v? What values do v1, v2, ... v5 have before replacing the values, or do they not exist at all yet?
No sorry, I mean in vector 1 so four elements of the v vector assign them in vector 1

Just shuffle your vector and then split it
v=v(randperm(length(v)))
V = mat2cell(v,1,[4 3 5 5 3])

+1 simple and effective.
I would recommend using a different name for the output: having two variables that differ only by case is just asking for bugs!
This worked perfectly thanks!
