The interpolation function for a given dataset is stored in a
gsl_interp
object. These are created by the following functions.
- Function: gsl_interp * gsl_interp_alloc (const gsl_interp_type * T, size_t size)
-
This function returns a pointer to a newly allocated interpolation
object of type T for size data-points.
- Function: int gsl_interp_init (gsl_interp * interp, const double xa[], const double ya[], size_t size)
-
This function initializes the interpolation object interp for the
data (xa,ya) where xa and ya are arrays of size
size. The interpolation object (
gsl_interp
) does not save
the data arrays xa and ya and only stores the static state
computed from the data. The xa data array is always assumed to be
strictly ordered; the behavior for other arrangements is not defined.
- Function: void gsl_interp_free (gsl_interp * interp)
-
This function frees the interpolation object interp.
