Double for loop with problems

I have a column vector temp of size 221 and another column vector x of size 2819. I want to create a new column vector from temp , of size 2819, inserting 12 zeros each number. Such as:

temp=
22
23
25
...

new_matrix=
22
0
0
0
0
0
0
0
0
0
0
0
0
23
0
0
0
0
0
0
0
0
0
0
....

But when I use a double for loop, an error appear: Subscripted assignment dimension mismatch. Error in vertices_automatic (line 109) new_matrix (j) = [temp(1:k(i),:); b; temp(k(i)+1:end,:)]

The double loop is:

for i=1:size_temp
    for j=1:size_x  
       k (i)= 0+i; %row position, can be 1,2 or 3 ....
       new_matrix (j) = [temp(1:k(i),:); b; temp(k(i)+1:end,:)]
    end
 end

Thanks

Then "temp" should be of size 13*220+1 = 2861, shouldn't it ?

Best wishes

Just do it without a loop:

temp=[22 23 25];
new_matrix=temp(:);
new_matrix(1,13)=0;%extend with zeros
new_matrix=new_matrix';
new_matrix=new_matrix(:);

(or you could just generate a matrix/vector with zeros and put in temp with indexing)

Thanks, it's a good solution !
