[responding to previous question about vectorizing pow() on both the
bases and the exponents -- I suggested<br>
an explicit for loop ... posting back to the list for
comment/correction]<br>

I think (not positive) that encapsulating for loops in ADMB doesn't
make things more efficient -- it just simplifies the code.<br>
(If you want, I think you can write your own function -- for example, I
*think* that if you put this in your GLOBALS_SECTION<br>
it should automatically overload the "pow()" function for vectorized
bases and exponents ... (based on previous contributions<br>
from the list).<br>
<br>
df1b2vector pow(const df1b2vector& v,const df1b2vector & x)<br>
{<br>
int mmin=v.indexmin();<br>
int mmax=v.indexmax();<br>
// ?? add check that vectors have the same extents ??<br>
df1b2vector tmp(mmin,mmax);<br>
for (int i=mmin;i<=mmax;i++)<br>
{<br>
tmp(i)=pow(v(i),x(i));<br>
}<br>
return tmp;<br>
}<br>
