If you find an expression that doesn't seem to evaluate correctly, one
of the first things to try is to examine the FullForm of the held
expression (to suppress its evaluation):
lA\[CenterDot]xtest //Hold//FullForm
{{a, b}, {c, d}} . {x, y} //Hold //FullForm
FullForm cracks a certain percentage of the problems presented in this
forum instantaneously!
