X = rand(1,100) ; % say your data or units
n = length(X) ;
% move in the order
A = X(1:60/100*n) ;
B = X(60*n/100+1:end) ;
% move in randomly
idx = randperm(n) ; % randomly arrange the indices
A = X(idx(1:60/100*n)) ;
B = X(idx(60*n/100+1:end)) ;

Yes... Indices idx should be used. Edited the code.
