Input of stepImpl is entire array when using step in a script
<p>If I use step(sys,x) in a script after constructing a system object, the entirety of x is passed through as a vector to stepimpl instead of sample by sample input.
On the other hand, if I perform step(sys,s) where s is a scalar instead and iterates this line of code, the state of 'sys' is reset on each call of step.</p>

<p>For example:</p>

<pre><code>SFTRLS_obj = SFTRLS;
for i = 1 : N
    step(SFTRLS_obj,d_dx(i),dx(i));
end
</code></pre>

<p>What is the proper way to use a system object in a script and 'propagate' input samples to the system object?</p>
