Details:

With the default format, this is the output for a multidimensional matrix,
with the spacing different for each slice:


octave:1> foo = mod ((1:4) + (1:4)' + 4*reshape(1:4,1,1,[]), 11)
foo =

ans(:,:,1) =

    6    7    8    9
    7    8    9   10
    8    9   10    0
    9   10    0    1

ans(:,:,2) =

   10    0    1    2
    0    1    2    3
    1    2    3    4
    2    3    4    5

ans(:,:,3) =

   3   4   5   6
   4   5   6   7
   5   6   7   8
   6   7   8   9

ans(:,:,4) =

    7    8    9   10
    8    9   10    0
    9   10    0    1
   10    0    1    2


It would be nicer if the columns were spaced evenly like this (look at the
third slice):


foo =

ans(:,:,1) =

    6    7    8    9
    7    8    9   10
    8    9   10    0
    9   10    0    1

ans(:,:,2) =

   10    0    1    2
    0    1    2    3
    1    2    3    4
    2    3    4    5

ans(:,:,3) =

    3    4    5    6
    4    5    6    7
    5    6    7    8
    6    7    8    9

ans(:,:,4) =

    7    8    9   10
    8    9   10    0
    9   10    0    1
   10    0    1    2


One partial workaround is to use "format short g" or "format long g" to align
but those use too much space per element.

I looked in the code for disp() but the formatting rules for number widths are
unclear to me.
