Hi,
what keeps frustrating me about Matlab - or my lack of Matlab skills that is..
How do I do this more nicely
tmp = get(gca, 'YLim');
set(gca, 'YLim', [0, tmp(2)]);
clear tmp;
% I would imagine something like this:
set(gca, 'YLim', [0, get(gca, 'YLim'){2}]);
It's not about this specific example, it's about how to avoid having to create a temporary variable in order to index the output. I could come up with a ton of other examples that have crossed my projects over the years.
here's another example which is obviously dumbed down. The idx will not be hardcoded obviously
CellWithStuff = {'one', 'two', 'three', 'four'};
tmp = contains(CellWithStuff, 'o');
OutputIWant = tmp(1);
% what I'm looking for is replacing
contains(CellWithStuff, 'o')[1] % accessing the first entry of the output somehow simpler...
I'm not a professional developer, so maybe there is an obvious solution to something like this.
I'd appreciate any suggestions!
Arnold

MATLAB doesn't support this capability natively, so the only thing you can do is live with it or use klunky workaround code.

hm.... not what I wanted to hear, at least I'm not entirely incapable of searching the web for answers then (I never found any).

CellWithStuff{find(contains(CellWithStuff,'o'),1)};
CellWithStuff(find(contains(CellWithStuff,'o'),1));%depending on what you want
