<p class="MsoNormal">Hi Barry<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">It’s a bit difficult to tell what you’re trying to do from that code snippet. I *<b>think</b>* you have 3 arrays : dcsi(Npod, Nsr), pod_7 (Npod * Nsr) and sr_7 (Npod*Nsr). You’re trying to replace values of pod_7 and sr_7 , where dcsi=700,
with monotically increasing numbers with a stride of 0.001. If so, then the following will do that eliminating the loop; I don’t think the where() function will help here though<u></u><u></u></p>

<p class="MsoNormal">This is assuming I’ve understood what you’re trying to do (and I’m not sure about that)….<u></u><u></u></p>
