How do I fix this error?

%$Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 0-by-1.
%$Error in machine_problem (line 39)

if states(j,1) == 0
[a]= 1;
elseif j >= (2^i)
[a] =0;
end
what if neither of those is true? What will a be initialized to?
x = find(states == (states(j,1)-capacities(i,1)));
How do you know that exactly one such location exists?
