code for cppad is as yet!) This code is about 25 times faster than the current<br>
ADMB code for a 2,000 x 2,000 matrix and about 4 times slower than the Openblas<br>
code which contains optimized assembler and Fortrash. Any suggestion for improvements<br>
would be welcome. Per usual I will hold my breath.<br>
