我随手编个m文件给你试试吧。编的有点复杂了。呵呵。

clear all;

data =rand(1,50);

N_div = 10;

nn =size(data); N=nn(2);

%%%% randomly redistribute this N numbers

IsRepeated = 1;

RDis(1) = 0;

for i =1:N

IsRepeated = 1;

while(IsRepeated == 1)

J = floor(rand*N+1) ;

if(i==1)

IsRepeated = 0;

end

if(i>1)

IsRepeated = 0;

for j=1:i-1

if(J==RDis(j))

IsRepeated = 1;

end

end

if(J>N)

IsRepeated = 1;

end

end

end

RDis(i) =J;

%%% insert random blocks between numbers (balls).

for i =1:N_div-1
