Hi Everyone,
I want to be able to refer to the information of my edit box (called edit_x) throughout my GUI's m file. My code is quite complicated. The idea is that whatever the user enters into the edit box is compared with the already loaded .mat files listed in the listbox (called listbox_x), and only those whose first n letters match those of the characters enterred by the user into the edit box will remain in the list box.
However, every time I try it out, it tells me that my edit_x is undefined.
If anyone could give me any guidance on this I would be extremely grateful.
Thanks,
Rosie
For reference, and to identify if I've done anything else wrong that's caused this error, I'll post my code below;
% --------------------------------------------------------------------
function varargout = listbox_x_CreateFcn(h, eventdata, handles, varargin)
D = dir('*.mat'); %Scan directory for .mat files
listbox_x_string = {D(:).name}; %Set to display full name of files found
set(h,'String',listbox_x_string); %Display list of files in ListBox_x
guidata(gcbo,handles)
% --------------------------------------------------------------------
function varargout = edit_x_Callback(h, eventdata, handles, varargin)
edit_x_string = varargin{1};
handles.edit_x_string = edit_x_string;
guidata(gcbo,handles)
% --------------------------------------------------------------------
function varargout = listbox_x_Callback(h, eventdata, handles, varargin)
listbox_x_oldstr = get(h,'String');
n = length(edit_x_string);
match_x = strncmpi(handles.edit_x_string,listbox_x_oldstr,n);
if n >= 1
if match_x == 0
set(h,'String',' ');
elseif match_x >= 1
set(h,'String',listbox_x_oldstr(match_x));
end
end
guidata(gcbo,handles)

In case anyone has the same issue I managed to fix the code by changing it to the following;
% --------------------------------------------------------------------
function varargout = listbox_x_CreateFcn(h, eventdata, handles, varargin)
D = dir('*.mat'); %Scan directory for .mat files
listbox_x_string = {D(:).name}; %Set to display full name of files found
set(h,'String',listbox_x_string); %Display list of files in ListBox_x
guidata(gcbo,handles)
% --------------------------------------------------------------------
function varargout = edit_x_Callback(h, eventdata, handles, varargin)
edit_x_string = get(h,'String');
guidata(gcbo,handles)
D = dir('*.mat');
listbox_x_string = {D(:).name};
match_x = strmatch(edit_x_string,listbox_x_string)
set(handles.listbox_x,'String',listbox_x_string(match_x))
guidata(gcbo,handles)

PLEASE HELP TO FIX LINE mdl .
clear
D =[8.3, 4.76, 4.79, 4.24, 3.69]; %m^2/s
t =[91, 180, 365, 730, 1095]; %days
Dref =D(1);%m^2/s
tref =t(1); %days
x=log((tref./t));
y=log((D./Dref));
mdl= fitlm(x,y,'y~x1-1');%linear regression formula
figure(1)
plot(mdl)
xlabel('ln(t_ref/t)')
ylabel('ln(D/D_ref)')
title('m calculation')
grid on
m = table2array(mdl.coefficients(1,1));
time=linspace (0,100,10000)
for i=1:length(time)
Dt(i,1)=Dref/(1-m).*(tref/365/time(i)).^m;
ke=1;
kt=1;
At(i,1)=(tref/365./time(i)).^m;
Dappc(i,1)=ke*Dref*kt*At(i,1);
end
figure(2)
ACI=loglog(time,Dt*365*24*60*60,'r','linewidth',2)
fib=loglog(time,Dappc*365*24*60*60,'m','linewidth',2)
xlabel('time,year')
ylabel ('diffusion coefficient,m^2/s')
ylim([10^-5,10^-2])
