Use App Properties to share your data within an app. That way, you don't have to keep loading the same variables. Consider loading your mat files in the statup function.
Now just pay attention to the error messages.
Unrecognized method, property, or field 'InputXAsistocalculateYAxisEditField_2' for class
Did you mean:
K>> app.InputXAsistocalculateYAxisEditField.Value
When I switch the drop down menu to P15 or P20, I get this error. Compare the code for these cases with the code for P10. What is different? P10 works. These don't.
Unrecognized method, property, or field 'property' for class 'matlab.ui.control.DropDown'.
Error in selecting_Checking_at_point/InputXAsistocalculateYAxisEditFieldValueChanged (line 66)
elseif (strcmp(,'P15'))
Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 453)
Error while evaluating NumericEditField PrivateValueChangedFcn.
As for why the values are not appearing in the Y Axis edit field, consider consulting the properties of an edit field. You should set a value using code very similar to what is used to read a value. Again, pay attention to names as well.
