Under matlab R2007b I see
>> a = ver('matlab')
a =
Name: 'MATLAB'
Version: '7.5'
Release: '(R2007b)'
Date: '02-Aug-2007'
>> a = ver('octave')
a =
0x0 struct array with fields:
Name
Version
Release
Date
The octave "ver" function doesn't take an argument. To get the
functionality you want this way you could modify Octave's ver so that it
assumes the argument is 'octave' if it is missing and then something like
if (strcmpi (pack, "octave"))
## Do what is already done, plus set ret if needed
else
lst = pkg("list");
ret = [];
for i = 1 : length (lst)
if (strcmpi (pack, lst{i}.name))
ret = struct ("Name", lst{i}.name, "Version", lst{i}.version,
"Release", [], "Date", lst{i}.date);
break;
endif
endfor
if (isempty (ret))
## How do you create an empty structure?
ret = struct ("Name", [], "Version", [], "Release", [], "Date", []);
ret(1) = [];
endif
endif
would get the type of behavior you want as long as someone doesn't
create an "octave" toolbox in matlab or a "matlab" package in octave.
