fx	factor for the partition in x-direction (fx*Nx will be rounded)
fy	factor for the partition in y-direction (fy*Ny will be rounded)
n	# of polynomial coefficients per dimension (1<=n<=20, note that the library is optimized for n=3 )
Nx	# of points in x
Ny	# of points in y

Parameters

bcx	boundary condition in x
bcy	boundary condition in y
