I want to store different values of t in I but I can't store via this code please help me
for j=0:4
U2 = makedist('Uniform','lower',200,'upper',600);
t=random(U2)
t=round(t)
I(:,j)=t
end

You started j as 0 and try to store into I(:,j) so you are trying to store in column 0. Matlab array index start at 1

Well, you can't use a value of zero (the first value j will have) to index into a matrix. Indices must be strictly positive integer. The simplest fix is to have j go from 1 to 5.
The whole line I(:, j)=t is very suspicious. t is scalar, so why have you got a colon (which would indicate you intended to store a vector)? I'd recommend you go through the tutorial to understand indexing.
Note that if all you want to generate is 5 integers between 200 and 600 using a uniform distribution, then randi is much simpler:
I = randi([200 600], 1, 5)
