Creating a function in Matlab GUIDE gui other then the auto generated callbacks

i have an issue.. i am new to matlab hence excuse me if my question is silly i have to generate the eucledian distance of two variables, hence i need to generate another function which calculates the eucledian value in the guide. i tried using the matlab function i.e.

 function [d, q, a, b, f] = extendedEuclidean_forward(m1,a1);

but it gave me an error. i have a function shares_callback in which i need to call this eucledian function

function Shares_Callback(hObject, eventdata, handles)
% hObject    handle to combineShares (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
M=m1*m2*m3;
a1=M/m1;
a2=M/m2;
a3=M/m3;

[d, q, a, b, f] = extendedEuclidean_forward(m1,a1);

end
please help, developing college project.

m1, m2, m3 are not defined in the scope of that callback.

The only variables in that scope at the start of the callback are hObject, eventdata and handles.

Most likely you want to have stored m1, m2 and m3 on the handles structure from wherever they came and then access them as

handles.m1, handles.m2, etc

Try making handles a variable in your function.

function [d, q, a, b, f] = extendedEuclidean_forward(handles,m1,a1);

And then call the fucntion via:

[d, q, a, b, f] = extendedEuclidean_forward(handles,m1,a1);

@adam i have done what you said.. that was an error..thanks ! @jason will implement and let you know
