Could you please elaborate by what you mean by units? Would it be a matrix or something like a table with multiple groups?

在 MATLAB Online 中打开

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)) ;
