Hello,
This might sound like a very basic question, but I've been struggling to
find how to properly format a matrix in Octave.
I want to display the values of a matrix using 2 decimal digits AND the
numbers in columns aligned on the decimal point. So far, "format bank" gives
me the closest output that I want, but displays the numbers in a rather
messy way.
Here's an example:
octave:71> format bank
octave:72> Ua
Ua =
-0.22 -0.11 0.29 -0.41 -0.11 -0.34 -0.52 0.06 0.41
-0.20 -0.07 0.14 -0.55 0.28 0.50 0.07 0.01 0.11
-0.24 0.04 -0.16 -0.59 -0.11 -0.25 0.30 -0.06 -0.49
-0.40 0.06 -0.34 0.10 0.33 0.38 -0.00 0.00 -0.01
-0.64 -0.17 0.36 0.33 -0.16 -0.21 0.17 -0.03 -0.27
-0.27 0.11 -0.43 0.07 0.08 -0.17 -0.28 0.02 0.05
-0.27 0.11 -0.43 0.07 0.08 -0.17 -0.28 0.02 0.05
-0.30 -0.14 0.33 0.19 0.11 0.27 -0.03 0.02 0.17
-0.21 0.27 -0.18 -0.03 -0.54 0.08 0.47 0.04 0.58
-0.01 0.49 0.23 0.02 0.59 -0.39 0.29 -0.25 0.23
-0.04 0.62 0.22 0.00 -0.07 0.11 -0.16 0.68 -0.23
-0.03 0.45 0.14 -0.01 -0.30 0.28 -0.34 -0.68 -0.18
What I would like to see is this:
Ua =
-0.22 -0.11 0.29 -0.41 -0.11 -0.34 -0.52 0.06 0.41
-0.20 -0.07 0.14 -0.55 0.28 0.50 0.07 0.01 0.11
-0.24 0.04 -0.16 -0.59 -0.11 -0.25 0.30 -0.06 -0.49
-0.40 0.06 -0.34 0.10 0.33 0.38 -0.00 0.00 -0.01
-0.64 -0.17 0.36 0.33 -0.16 -0.21 0.17 -0.03 -0.27
-0.27 0.11 -0.43 0.07 0.08 -0.17 -0.28 0.02 0.05
-0.27 0.11 -0.43 0.07 0.08 -0.17 -0.28 0.02 0.05
-0.30 -0.14 0.33 0.19 0.11 0.27 -0.03 0.02 0.17
-0.21 0.27 -0.18 -0.03 -0.54 0.08 0.47 0.04 0.58
-0.01 0.49 0.23 0.02 0.59 -0.39 0.29 -0.25 0.23
-0.04 0.62 0.22 0.00 -0.07 0.11 -0.16 0.68 -0.23
-0.03 0.45 0.14 -0.01 -0.30 0.28 -0.34 -0.68 -0.18
What format or command can I use to make Octave display matrices in this
way? (i.e. columns aligned on the decimal point using 2 decimal digits)
I'm using Octave version 3.6.4 on Ubuntu 13.04
Thanks,
AMG
