from_node_list_to_elem_matrix

from_node_list_to_elem_matrix

Convert list of properties associated to nodes to matrix of properties associated to elements based on the connectivities

The ‘ith’ value of the ‘node_list’ array stores the property of the ‘ith’ node. The ‘jth’ ‘kth’ value of the ‘elem_matrix’ array stores the property of the ‘kth’ node within the ‘jth’ element

param node_list:
 Properties of the nodes
type node_list:np.array
param connectivities:
 Connectivities between the nodes to form elements
type connectivities:
 np.array
returns:Properties of the elements
rtype:elem_matrix (np.array)
