Extracting the first three minimum elements from a vector v and assign them to h then letter remove the elements from vector v and used the index to removed some element in vector w.

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;
trying to take the first three minimum elements in vector v and assigned the values to h, and after then, remove those elements from v, and use index of the removed elements of v, to remove some elements in w.
e.g v=

Can you show us what output you are expecting?

Attempted to access h(4); index out of bounds because numel(h)=3.

Error in Untitled (line 7) if v(i)==h(i)

Why you are running a while loop?

k = sort(v) ;
h = k(1:3) ;

That's enough eh..

I also want to remove the elements I vector v.

[KSSV]

YOu want to remove those minimum three elements from v?

[Bashir Yusuf Bichi]

yes, from v

Answer 1

[Bashir Yusuf Bichi]

v(h)=[];
w(h)=[];

thanks @KSSV, I got it. I don't have to use the while loop.

Answer 2

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))=[]
