I wrote the original dvariable spline code in about a half a day

that doesn't mean anything)<br>
although an unoptimized one could have been done in 10 minutes. Why
is this rocket science?<br>
I hate going backwards.<br>

anyone have documentation on how cubic splines are
implemented in ADMB?<br>
Or a simple description of how cubic splines are
implemented in general.<br>
<br>
<br>
<br>
There are some examples on how to use them in ADMB<br>

Subject: [ADMB Users] 10.1 ic > imax<br>
<br>
Hi folks<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I've recently installed admb 10.1 on
a 'real' system (SuSE Linux Enterprise<br>
Server 11 SP1, gcc 4.3) and I've noticed different
behaviour vs my 32-bit<br>
admb 10.0 windoze setup. Specifically the ic > imax
is minimum attained<br>
issue pops up on the 10.1 where it does not on the 10.0.
Both installations<br>
give me the same parameter estimates, but obviously a)
something is<br>
different, b) it appears to be worse in the newer
version and c) it would be<br>
nice to know why. The first thing that came to mind is
that the default<br>
value of the convergence criterion might have changed
between 10.0 and 10.1<br>
but I ran the new system with -crit 1e-4 and same
behaviour.<br>
<br>
Any ideas?<br>
