Hi all,
I made a checkbox app that I intend to execute automatically in my script.
This is what I intend to do with the app. That is, if I tick any of the above, it will replace all vector values to nan in that particular cell.
% Callbacks that handle component events
methods (Access = private)
% Value changed function: RectusFemorisCheckBox
function RectusFemorisCheckBoxValueChanged(app, event)
value = app.RectusFemorisCheckBox.Value;
for i = 1:length(rec_fem_cycle)
rec_fem_cycle{i}=nan;
end
end
% Value changed function: VastusMedialisCheckBox
function VastusMedialisCheckBoxValueChanged(app, event)
value = app.VastusMedialisCheckBox.Value;
for i = 1:length(vas_med_cycle)
vas_med_cycle{i}=nan;
end
end
as above for each of the cells
However I get the following error. I suspect this is something to do with the fact that app does not recognize the cell (I do have these cells in my workspace though);
K>> ignore_noise
Unrecognized function or variable 'rec_fem_cycle'.
Error in ignore_noise/BicepsFemorisCheckBoxValueChanged (line 49)
for i = 1:length(rec_fem_cycle)
Error in matlab.apps.AppBase>@(source,event)executeCallback(appdesigner.internal.service.AppManagementService.instance(),app,callback,requiresEventData,event) (line 63)

You can add properties to your app and assign values to them, for example when the app is initialized. Then inside of your callbacks you can utilize these property values using the syntax, app.myProperty
