Here is problem 3.97, solved using matlab. In this case, the entire problem is solved using vectors (and Ax=b to solve) in Matlab.

Here is problem 4.68, solved using matlab. In this case, the entire problem is solved using vectors (and Ax=b to solve) in Matlab.

Problem 5.4 has been solved two ways in Matlab. In this first case, the equations were set up on paper and A and b were typed into matlab to solve. In the second case, the entire problem is solved using vectors (and Ax=b to solve) in Matlab - note that here you have to pay close attention to which vector components belong in which spot in A and b.

Here is a 3D rigid body equilibrium problem, solved beginning to end in matlab, using vectors and symbolic notation:*Engineering Mechanics: Statics, Meriam and Kraige, 2007.*
