[Maxima-discuss] new flags for matrix elements padding for pretty printer display

[Robert D. <rob...@gm...>]

I've pushed some commits to src/displa.lisp to implement two more
display flags, display_matrix_padding_vertical and
display_matrix_padding_horizontal.

By default, matrix elements are displayed with space between rows and
space between columns. These new flags enable (default) or disable
that spacing.

I've attached some simple examples as an image (I couldn't figure out
a way to disable Gmail composer's interline spacing). This image shows
what I see in a terminal on an Ubuntu system.

For more extensive examples, you can try, after building the current
version from GIt:

batch ("tests/test_matrix_display.mac");

which shows a lot of examples of the recently-created display flags
for boxes and matrices.

I think this will be useful. Any comments are welcome.
