[ADMB Users] bounded_vector elements

[Steve Martell]

Yes read the manual on init_bounded_number_vectors

DATA_SECTION
init_int n
// ...
PARAMETER_SECTION
// need to create some vectors to hold the bounds and
// phase numbers
LOC_CALCS
dvector lb(1,n);
dvector ub(1,n);
ivector ph(1,n);
// get the desired values into lb,ub,ph somehow
lb.fill_seqadd(1,0.5);
ub.fill_seqadd(2,0.5);
ph.fill_seqadd(1,1);
END_CALCS
init_bounded_number_vector a(1,n,lb,ub,ph)
