Use indexing.

a = [1 2 3];
b = [4 5 6];
c = horzcat(a, b);  % [EDITED]: horcat->horzcat

anew = c(1:3);
bnew = c(4:6);

thank you.

Btw. HORZCAT is the same as including the arguments in [ and ], so this:

a = [1, 2, 3]

is equivalent to

a = horzcat(1,2,3)

[Glo]

can this be done in simulink by some block?
