## Description

General function for querying information about integration method objects.

## Command list

- `b = gf_integ_get(integ I, 'is_exact')`

  Return 0 if the integration is an approximate one.

- `d = gf_integ_get(integ I, 'dim')`

  Return the dimension of the reference convex of the method.

- `n = gf_integ_get(integ I, 'nbpts')`

  Return the total number of integration points. Count the points for the volume integration, and points for surface integration on each face of the reference convex. Only for approximate methods, this has no meaning for exact integration methods!

- `Pp = gf_integ_get(integ I, 'pts')`

  Return the list of integration points Only for approximate methods, this has no meaning for exact integration methods!

- `Pf = gf_integ_get(integ I, 'face_pts',F)`

  Return the list of integration points for a face. Only for approximate methods, this has no meaning for exact integration methods!

- `Cp = gf_integ_get(integ I, 'coeffs')`

  Returns the coefficients associated to each integration point. Only for approximate methods, this has no meaning for exact integration methods!

- `Cf = gf_integ_get(integ I, 'face_coeffs',F)`

  Returns the coefficients associated to each integration of a face. Only for approximate methods, this has no meaning for exact integration methods!

- `s = gf_integ_get(integ I, 'char')`

  Ouput a (unique) string representation of the integration method. This can be used to comparisons between two different integ objects.

- `gf_integ_get(integ I, 'display')`

  displays a short summary for a integ object.
