I am trying to write a status to a gui edit textbox. I am using the following command using: "set(handles.Status_disp,'Noise Ananlysis started ...')" I get an error.

K>> set(handles.Status_disp,'Noise Analysis started ...')
Error using matlab.ui.control.UIControl/set
There is no Noise Analysis started ... property on the UIControl class.
>> handles.Status_disp
Undefined variable "handles" or class "handles.Status_disp".

Jeffrey - please copy and paste the function (signature and body) that is throwing the error. From what you have shown above, it looks like you have put a breakpoint in your code and are trying to execute

set(handles.Status_disp,'Noise Analysis started ...')

Which function are you trying to run this command from? Is the handles structure defined?

Looking at the error message, it seems that issue is related to incorrect usage of the 'matlab.ui.control.UIControl/set' method. The following command may be a potential correction.

set(handles.Status_disp,'String','Noise Analysis started ...')

If this doesn't resolve the error, as Geoff mentioned, it may be more helpful if the details of the handles structure and surrounding code are available.
