I'm assuming this is in a MATLAB Function block? How does your MATLAB code in the block define 'err1'?

You could get that if your code builds up "err1" dynamically, something like
err1 = [];
for K = 1 : 10
err1 = [err1 K];
end
Instead you should allocate err1 as the maximum size immediately on the first assignment to it. I seem to recall that you can reduce the size later, but not increase it.
