variable name by cancatation in matlab

I want to set

c1=1;
c2=4;
c3=9;
c4=16;

How to do this in the following way

for i=1:4
  ci=i^2;
end

i.e i will vary to generate c1, c2, c3, c4 etc. from ci.

Don't use separate variables with different names. Use an array:

ci = [1:4].^2

If you really want to do it the for loop way, do this:

for k = 1 : 4
  c(k) = k ^2;
end

Actually my actual problem is another one. I have just given an example. I just want to know how to change the variable name through a loop.
