Dear lyx users and developers,
a few weeks before deadline, i have a problem with aligning formulas
that should also be enumerated.
In order to align the formulas, i tried to use array environment (second
from the right in the middle row of the math-panel). The outcome looked
real nice in LyX, but quite different in the generated postscript: the
sum-index does no longer appear underneath the sum-symbol (but like it
would in a normal text context).
1. Does anyone know a solution to that ?
2. And, how do i produce an eqnarray (witout typing LaTeX) under LyX ?
3. How do i include a multi-page PostScript image in my document ?
Thanks
Martina
