Details:

This is a follow-up of bug #50543 (comments 7 to 11).

Given a binary file, a text file and a non-existing file:


dd if=/dev/urandom of=random.dat count=100 # file: data
echo blah blah blah > random.text # file: ASCII text


Matlab's behavior is:


>> open nonexisting.file
Error using open (line 86)
File 'nonexisting.file' not found.
>> open random.dat
% try to display data in the variable editor
>> open random.text
% open file in Matlab's text editor


while Octave does nothing for a binary or non-existing file and opens the text
file in the system's text editor (not Octave's).
