Would it be bad style to use in displaymode an array with three colums that are right-center-left ("rcl") oriented instead of eqnarray, to typeset systems of differential of equations ?
The spacing between the columns then seems to look like and eqnarray - but the spaces between the rows are then less than in eqnarray and all the fractures are textsize, not normal size.
The reason have used this was because by using an array, I can reference the whole system with a single number, not just lines at a time. The reference number would thus be displayed on vertically in the middle and not near a specific line, like when using eqnarray. Is there a way to also reference a whole system when using eqnarray ?
amsmathprovides many environments for aligning equations. – Heiko Oberdiek Apr 09 '15 at 06:38eqnarrayshould be a non-aim, it is really one of the poorer parts of the base latex system. Always use the amsmath alignments instead, they provide the features you ask for here. – David Carlisle Apr 09 '15 at 07:34amsmathpackage and use asplitenvironment inside anequationenvironment. – Mico Apr 09 '15 at 08:21
