When I run the main function from mscript, it puts the variables in the workspace which I can access them in GUI using "evalin". How do I put the variables in the GUI workspace without running the main mscript file from a command window?

function PushMe_Callback(hObject, eventdata, handles)
set(handles.output_line,'String','I Got here');
Get_Length(Note_Vector,output,Counter,Total_num)
%------------------------------------------------------------
function Get_Length(Note_Vector,output,Counter,Total_num)
output = [ ];
while (1)
T = Total_num - Counter;
for j=1:T
[xml_input]=Get_Note(Note_Vector(j));
output = [output xml_input];
end
end

Please post the question in the section for the question, while the title should be a short title only.

There are no functions in a script. And the variables in a script are put into the base workspace directly - you do not need to use evalin() or assignin() or anything like that. Conversely, a function in an m-file will put the variables into the private workspace of that function. They are used by the function and vanish when the function exits. You should not use evalin or assignin inside the function (except under some fairly rare situations). If you want some variables in the function to be returned to the calling routine, then you have to define one or more output arguments:
function [output1 output2] = Get_length(input1, input2, input3, etc)

The function guidata can store variables inside the ApplicationData of a figure, such that they are available in all callbacks. You find guidata in the help and doc of Matlab and hundreds of examples in this forum.

@Eric: The code you have posted does not contain the variable "output1", which appears in the error message. But without seeing the line, which causes the error, we cannot guess the cause of the problem.
