MATLAB uniform ticks (uniformticks) and printing

The following script can make the axes nicer. Example:

%% render uniform ticks digits on Y axis
function uniformticks_y(deci) ; % input number of decimals as string
command = ['%0.' mat2str(deci) 'f|'] ;
ticks = get(gca, 'Ytick') ;
set(gca, 'YTickLabel', sprintf(command, ticks));

However, changing the graph manually in the GUI can upset the nice axes settings. Simply rerun the script from the console without closing the graphs.

convert graph image to text data

To convert a screenshot, photo or scan of a graph or plot to a text data table, use this software:

bash copy a directory recursively, excluding some directory or file name

rsync -av --progress sourcefolder /destinationfolder --exclude thefilenametoexclude

rsync -av --progress sourcefolder /destinationfolder --exclude thefoldertoexclude

NOTE: if the filename or directory appear multiple times, they will be excluded multiple times

bash config files

For this task, you don't have to write fat parser routines (unless you want it 100% secure or you want a special file syntax) - you can use Bash's source command. The file to be sourced should be formated in key="value" format, otherwise bash will try to interpret commands:

#!/bin/bash
echo "Reading config...." >&2
source /etc/cool.cfg
echo "Config for the username: $cool_username" >&2
echo "Config for the target host: $cool_host" >&2

So, where do these variables come from? If everything works fine, they are defined in /etc/cool.cfg which is a file that's sourced into the current script or shell. Note that this is not the same as executing this file as a script! The sourced file most likely contains something like:

cool_username="guest"
cool_host="foo.example.com"

These are normal statements understood by Bash, nothing special to do. Of course (and that is a big disadvantage under normal circumstances) the sourced file can contain everything that Bash understands, including evil code!
