Similar to the previous sections, the column matrix of generalised coefficients, {a}, is obtained by evaluating

where, by arranging the dof. in the above sequence enables suitable partitioning of [A] and minimises the effort required to obtain the inverse. Unlike the previous treatment of the rod and beam element, the evaluation of [A]-1 is delayed until Example 9.5. The result, however, is given by eqn. (9.88). It is hoped this departure will enable the element formulation to be more easily assimilated.
