I am given a truss with a data structure jointInfo(n). jointInfo(n).xy is the coordinates, jointInfo(n).connectedMembers is the indexes of members connected to nth joint, jointInfo(n).connectedJoints is the indexes of other joints connected to the nth joint by members, and the external forces. Also given a memberJoints matrix with memberjoints listing joints connected by each member. I would set it up as Ax=b and I got the b part which is external forces. How could I set up the A matrix? Should I use some nested for loops? Any ideas?
