Description

This object facilitates one-dimensional integration by employing a function pointer to evaluate the integrand. It's worth mentioning that this object is not well suited for serialization or for integration with GObject introspection bindings, as it relies on raw function pointers.

Functions

NcmIntegral1dPtrF ()

gdouble
(*NcmIntegral1dPtrF) (gpointer userdata,
                      const gdouble x,
                      const gdouble w);

ncm_integral1d_ptr_new ()

NcmIntegral1dPtr *
ncm_integral1d_ptr_new (NcmIntegral1dPtrF F,
                        GDestroyNotify userfree);

Creates a new NcmIntegral1dPtr object for the integrand F .

Parameters

F	a NcmIntegral1dPtrF.	[scope notified]

                             const gdouble reltol,
                             const gdouble abstol,
                             const guint partition,
                             const guint rule);

Creates a new NcmIntegral1dPtr object for the integrand F .

userfree	GDestroyNotify.	[scope notified]
reltol	the relative tolerance
abstol	the absolute tolerance
partition	the maximum subdivisions
rule	integration rule to use in each subinterval

Returns

the new NcmIntegral1dPtr object.

[transfer full]

ncm_integral1d_ptr_ref ()

NcmIntegral1dPtr *
ncm_integral1d_ptr_ref (NcmIntegral1dPtr *int1d_ptr);

Increases the reference count of int1d by one.

Parameters

a NcmIntegral1dPtr

Returns

int1d .

[transfer full]

ncm_integral1d_ptr_free ()

void
ncm_integral1d_ptr_free (NcmIntegral1dPtr *int1d_ptr);

a NcmIntegral1dPtr

ncm_integral1d_ptr_clear ()

void
ncm_integral1d_ptr_clear (NcmIntegral1dPtr **int1d_ptr);
