I have a function which should be executed if a button is pressed and two values should be returned
in function file:
function [x,y] = MySimple_Edgee(res,ch,thres,edg,ac_coup,dc_coup,range,analog_offset)
in app file:
[app.a,app.b]=MySimple_Edgee(app.Resolution,app.Channel,app.Threshold,app.Edge,app.AC,app.DC,app.Range,app.anOffset;
plot(app.UIAxes,app.a,app.b);
error message is given: Too many output arguments

Is it somehow possible that app is non-scalar at that point so app.a would be expansion ?

To call your function saved as a script from appdesigner just place the script file in a folder named 'private' that has to be placed beside the *.mlapp file (just to be in path). The syntax will be
[x,y] = MySimple_Edgee(res,ch,thres,edg,ac_coup,dc_coup,range,analog_offset)
To integrate the function in your mlapp app save it as private function
function [x,y] = MySimple_Edgee(app,res,ch,thres,edg,ac_coup,dc_coup,range,analog_offset)
and call it like
[x,y] = app.MySimple_Edgee(res,ch,thres,edg,ac_coup,dc_coup,range,analog_offset)
