3 years ago Yes, that looks like a typo. Thanks for catching that. It has been corrected in dc99713 commit.
For now, just declare the function correctly in the GLOBALS_SECTION.
GLOBALS_SECTION
#include <statsLib.h>
dvar_vector cubic_spline(const dvar_vector& spline_nodes, const dvector& ip);
Got the following linker error when trying to compile and link examples/contrib/catage/catage.tpl on a Mac using ADMB 12.3:

The example in examples/admb/catage compiles and runs correctly, but (of course) doesn't have a call to cubic_spline(...).
The signature for "cubic_spline(dvar_vector const&, dvar_vector const&)" is defined in stats lib.h but the body of the function is not defined anywhere (at least, I couldn't find it using the ADMB Documentation File Reference). Note that the body of the function "cubic_spline(dvar_vector const&, dvector const&)" IS defined in vcubicspline.cpp (but the signature does not seem to appear in a header file).
