Write a matrix equation TM + F = 0, where T is the
matrix of direction cosines,
M are the unknown member and reaction forces and F is the vector of
known external forces applied to the truss.
The matrix equation will be used in matlab, I can input it myself but I am having issues forming that actual correct matricies.
