Rationalised local and global optimisations. Fixes presentation of locally optimised code (ode view). Much more elegant :-) check-in: e5dbca659d user: geraint@users.sourceforge.net tags: origin/global-optimisation, trunk | |

Does not now attempt optimisation if matrix has zero length. Declaration of matrix size is left to def.r. check-in: a3d8883875 user: geraint@users.sourceforge.net tags: origin/global-optimisation, trunk | |
