Save arrow vector which changes its length during a loop

Hey!

I'm trying to save on my workspace an arrow variable (I & J) which shanges its length during the loop.

Hope you can help me!

for i=1:6 
    DR_min(i)=min(DR_new);
    [row]=find(DR_new==DR_min(i));
    I=IQ(row);
    J=JQ(row);
    DR_new(DR_new<=DR_min(i)) = NaN;
    shells(i)=length(I)/16;
end

I am not sure what your question is. If it is a matter of saving all the I and J values in the workspace, just index them like this;

for i=1:6 
    DR_min(i)=min(DR_new);
    [row]=find(DR_new==DR_min(i));
    I(i)=IQ(row);    %added (i) index
    J(i)=JQ(row);
    DR_new(DR_new<=DR_min(i)) = NaN;
    shells(i)=length(I)/16;
end

If I and J change their size you should use a cell array:

I = cell(1,6);
J = cell(1,6);
for i=1:6 
    DR_min(i)=min(DR_new);
    [row]=find(DR_new==DR_min(i));
    I{i}=IQ(row);   
    J{i}=JQ(row);
    DR_new(DR_new<=DR_min(i)) = NaN;
    shells(i)=length(I)/16;
end

Thank you guys, it helped me a lot, cell array helped me!
