Re: Matrix Column Vertical Spacing

[Douglas McIlroy]

Here's what I think is happening.

Each element of a row appears to be typeset on the same baseline.

It looks as if the baselines of adjacent rows are separated by the
maximum of the separations that would be needed in each column. This
assures that no entries collide with each other--the tightest packing
consistent with the notion of baseline.

I think what most of us expect is that the separation should be the
maximum excursion below baseline in the upper row plus the maximum
excursion above baseline of the lower row plus a standard gap. This
assures that there is a horizontal band of white space between
adjacent rows.

I haven't experimented to see whether the ultimate baseline
separations are equalized throughout the matrix or vary by row.
