Determine whether setting has active value set
Since R2024a
hasActiveValue(s)
hasActiveValue(s) returns 1 if the setting has an active value set. Otherwise, hasActiveValue returns 0.
s
1
hasActiveValue
0
example
collapse all
Add custom settings group with one setting. Confirm that it has no active value by default.
s = settings; g = addGroup(s,"mysettingsgroup"); addSetting(g,"OfficeNumber"); hasActiveValue(g.OfficeNumber)
ans = logical 0
Set the personal value for the OfficeNumber setting, which updates the active value.
OfficeNumber
g.OfficeNumber.PersonalValue = "East205";
Use a conditional statement to confirm that OfficeNumber now has an active value and, if so, return that value.
if ~isempty("g.OfficeNumber") && hasActiveValue(g.OfficeNumber) value = g.OfficeNumber.ActiveValue else disp("OfficeNumber has no active value.") end
value = "East205"
SettingsGroup
Setting, specified as a SettingsGroup object. Use the settings function to access the root settings group object and all the available settings in the tree.
