This function produce Quadratic serendipity shape function using barycentric coodinate.
The procedure for this shape function is proposed at 'Mathematics of computation, 2014, vol.83, no.290, pp2691-2716' Alexander Rand, et al.
They proposed this scheme for arbitrary polygon. And the generalized barycentric coordinate is used.
Especially, two type of Barycentric coodinates are fulfilled, Wachspress coordinate & Mean value coodinate.
There are 6 m-files in attached zip file.
- get_val_shape_fn_barycen.m : main function
- get_val_lambda.m : subfunction for calculating 'lambda'
- get_val_mu.m : subfunction for calculating 'mu (lambda * lambda)'
- get_val_xi.m : subfunction for calculating 'xi (extract some function to get serendipity family)'
- get_val_phi.m : subfunction for calculating 'phi (some modification for xi)'
- get_coord_vicinity_ab.m : subfurction for 'get_val_xi.m'
