Cleared out mttx array ans use mkid instead. check-in: 306da586dd user: gawthrop@users.sourceforge.net tags: origin/master, trunk

Changed mttxx to mttx - in implicit integration smx is called once
with x in the linearisation the same as x in the current state check-in: da7781f1c7 user: gawthrop@users.sourceforge.net tags: origin/master, trunk
