I have a matrix of node coordinates and forces, and a matrix of edges. How should I go about forming a global stiffness matrix, preferably through a for loop, using these matrices?

To form a global stiffness matrix, first create the element stiffness matrices for each element using the element's nodal coordinates and material properties. Then, assemble these element stiffness matrices into the global stiffness matrix by looping through each element and adding its contributions to the appropriate locations in the global matrix. Then, use the nodal connectivity information from the matrix of edges to determine which nodal displacements are associated with each degree of freedom in the global stiffness matrix. You may use the nodal forces to incorporate any externally applied loads.
