Description dma2002 2008-04-17 20:14:20 UTC
We have two matrixes which have corresponding sizes for desired mathematical
operation. In my example (look the attachment) I used popular case: square
matrix is multiplied by a vector. In this case, 4, 5, 6 and b (middle horizontal
items) should stay on the same line. Math aligns both matrixes by their centers,
but it isn't correct.
The task is to show Math, that this two matrixes depend one from another. Then
Math should align both matrixes correctly - by their middle horizontal items.
The same situation - while using more than two matrixes and using another
mathematical operations.

One more comment to the first message. Not only middle horizontal items should
stay on the same line but the other ones too. So, 1, 2, 3 and a should stay on
the same line; 7, 8, 9 and fraction c/d - too. After that both matrixes should
have the same height. Hence, brackets (if needed) will too.

Issue confirmed + me on CC  

The maths objects are turned into pictures, and pictures are centered, not their content.

FYI, there is a work in progress, who aims to solve unaligned formulas, and matrix is one case through 

Thanks to use aqua btw  ;-)

MRU->TL: could you please make an evaluation if this could be possible for the
formula parser? Thanks!
