problem in Matrix Indexing

Hi, below code i am trying to read matrix elements from an array of elements. i should get 5x3 matrix like

     1     2     3
     1     2     3
     1     2     3
     1     2     3
     1     2     3

but i am gettting like below

     1     2     3
     1     2     3
     1     2     3
     1     2     3
     3     3     3

i understand there is some problem with indexing.

Please help me in getting this.

i got some answer saying that to remove f(i,:)=k(x) if i do that f is 1 2 3 it is only 1X3 matrix i need it to be 5X3.

i dont want to use repmat because i have to use this in other context where i can not use.

 Thanks,

Sita

n=5; v=3; k=[1 2 3];

for i=1:n

    x=0;        
      for j=1:1:v
       x=x+1;
       f(:,j)=  k(x);
      end      
    f(i,:)=k(x)

end

Remove

 f(i,:) = k(x);

The result of your loop will be a 5x3 matrix. It will be a 1x3 matrix only on the first iteration. Consider preallocating for speed.

n=5; v=3; k=[1 2 3];
for i=1:n
      x=0; 
      for j=1:v
       x=x+1;
       f(i,j)=  k(x);
      end      
end

Well, if you insist not to use repmat (why??), I'd do it like this:

f = zeros(n,v);
for i = 1:v
    f(:,i) = k(i);
end

Or:

k = [1,2,3];
f = k(ones(1,v), :);
