v=[3,6,1,7,9,4];
w=[3,2,7,1,9,5];
[x,y]=sort(v);
h=x(1:3);
i=1;
while i<=numel(v)
if v(i)==h(i) % here h will be less than the elements in v, so it give me error
v(i)=[];
else
v(i)=v(i);
end
i=i+1;

v(h)=[];
w(h)=[];
thanks @KSSV, I got it. I don't have to use the while loop.

v=[3,6,1,7,9,4];
[k,idx] = sort(v) ;
h = k(1:3) ;
%%Remove from k
k(1:3) = []
%%Remove from v
v(idx(1:3))=[]
