Include the Matheron estimator in pykrige

Question

Hi I have another question: how can I include the Matheron estimator in my program and still use Pykrige?

My program looks like this:

from pykrige.ok import OrdinaryKriging
from pykrige.kriging_tools import write_asc_grid
import pykrige.kriging_tools as kt

x = np.array([-100, 280, -290, 23, 101, 110])
y = np.array([54, 100, 590, 470, 200, 25])
z = np.array([29.3, 21.0, 19.2, 29.1, 21.9, 23.1])

Ok = OrdinaryKriging(
    x,
    y,
    z,
    variogram_model='exponential ',
    verbose= True,
    enable_plotting= True
)

gridx =np.arange(-300, 300, 10, dtype='float64')
gridy =np.arange(0,600, 10, dtype='float64')
zstar, ss = Ok.execute("grid", gridx, gridy)

cax = plt.imshow(zstar, extent=(-300, 300, 0, 600), origin='lower')
plt.scatter(x, y, c=z, marker=".")
cbar = plt.colorbar(cax)
plt.title('Test Interpolation')
plt.show()
