Hi Julien,
The NAG functions are accessible from Origin C, and not directly from the interface. So if you want to use the NAG functions, first you need to add an Origin C function to your workspace. For example, if you define and compile the following function:
#include <origin.h>
#include <NAG\OCN_s.h> // include appropriate NAG header file double
double bessel_k0(double x)
{
return nag_bessel_k0(x)
}
The name bessel_k0 used here is arbitrary - you can call it what you want.
Once this function is set up, then you can use it to set column values, plot in new function window etc, by accessing it, such as:
col(b)=bessel_k0(col(a))
or bessel_k0(x) in function window etc.
Not sure of your problem no. 2 - someone else will respond.
