MATLAB: Change string of static text boxes whose tag contains “Output”

cleareditboxemptyresetstatic text

Hi all,
I am writing some analysis software in 2015a with GUIDE.
I am looking to push a button that will reset the GUI to how it opened, emptying (by setting string) ALL edit boxes (easy) and all static text fields that are used as an output. I do not want to empty static text boxes whose tag contains "Text" as these are GUI labels next to edit boxes.
Currently I have the code below, but I don't know how to adapt it for the above…
% Empty All Static Text Boxes Whose Tag Contains "Output"

set(findall(handles.figure1,'Tag','Output'),'string',''); % findall finds invisible objects as well (findobj does not)
My previous attempt was:
% Get All Static Text Tags
AllStaticTextTags = findall(handles.figure1,'style','text')
% Find All Static Text Tags Containing "Output"
StaticTextTagsContainingOutputIdx = contains(AllStaticTextTags,'Output'); % returns 1 if contains it 0 if not
StaticTextTagsContainingOutput = AllStaticTextTags(StaticTextTagsContainingOutputIdx);
% Empty All Static Text Boxes Whose Tag Contains "Output"
set(StaticTextTagsContainingOutput,'string','');
But understandably that doesn't work due to:
Undefined function 'contains' for input arguments of type 'matlab.ui.control.UIControl'.
Currently I am closing the window and re-running the main script but this is slow and inefficient.
EDIT: To clarify, the tags contain other letters also… I am looking to ONLY empty strings of static text boxes that have "Output" in their tag name.
Thanks,
Matt.

Matt - the function contains looks to have been introduced in r2016b so that function is most not likely available to you (given that your version is r2015a).
You can try the following though. Continue as before to get all the handles to the static text controls
 allStaticTextHandles = findall(handles.figure1,'style','text');
Then get the tags for each one (note that I'm using code for r2014a so it may be different for your version)
 allStaticTextTags = get(allStaticTextHandles, 'Tag');
And now you could use strfind to find those tags that contain the string 'Output'. The result of
 strfind(allStaticTextTags, 'Output')
will be a cell array of empty arrays or indices of where the string 'Output' starts in the tag. For example,
 ans = { []; [5]; []}
and so you would need to find which of these is non-empty and then clear the contents of that static text control.
