pysdic.Connectivity.to_array

Connectivity.to_array()

Convert the connectivity to a NumPy array of shape \((N_e, N_vpe)\).

Note

The returned array is a copy of the internal elements array. Modifying it will not affect the original connectivity.

See also

• elements() property for accessing and modifying the elements of the connectivity.

• from_array() class method for creating a Connectivity object from a NumPy array.

Returns:

A NumPy array of shape \((N_e, N_vpe)\) containing the elements of the connectivity.

Return type:

numpy.ndarray

Examples

Creating a Connectivity object from a random NumPy array.

import numpy as np
from pysdic import Connectivity

# Create a random connectivity with 100 elements
random_elements = np.random.randint(0, 100, size=(100, 4))  # shape (100, 4)
connectivity = Connectivity.from_array(random_elements)

Convert back to a NumPy array using the to_array method.

# Convert the connectivity back to a NumPy array
elements_array = connectivity.to_array()
print(elements_array)
# Output: A NumPy array of shape (100, 4) containing the elements of the connectivity.
