Hi, I am a bit confused, how to store the values in a matrix while using for loop. Here is the my code

k=1.5:0.1:3;
  ws=zeros(1,length(k));
  dof=zeros(1,length(k));
  for i=1.5:0.1:3
      ws=22+4+7+i;
   dof(i)=2+ ws;
  end

I want to store the values pf 'ws' and 'dof' in matrix. Thanks

k=1.5:0.1:3;
n = numel(k);
ws=zeros(1,n);
dof=zeros(1,n);
for ii=1:n
    ws(ii)=22+4+7+k(ii);
    dof(ii)=2+ ws(ii);
end

or just

ws = 33 + k;
dof = ws + 2;

You have to give the position where you want to write, like this:

k = 1.5:0.1:3;
ws = zeros(1,length(k));
dof = zeros(1,length(k));
for cpt = 1:length(k)
    ws(cpt) = 22+4+7+k(cpt);
    dof(cpt)= 2+ws(cpt);
end

But you don't need a loop to do this and it would be better to do simply:

k = 1.5:0.1:3;
ws = 22+4+7+k;
dof = 2+ws;
