 | hi all
i am trying to run a FOR loop in a GUI whereby i will select some
images in a listbox and they are to be displayed in the axes when the
for loop is running.
here are my codes
index_selected = get(handles.listbox1,'Value');
[rows cols]=size(index_selected);
for i=1:cols
file_list = get(handles.listbox1,'String');
file_list
filename = file_list(index_selected(i)); % Item selected in list
box
filename
axes(handles.axes1);
imshow(filename)
end
however, the program had problem when executing the
"imshow(filename)" part..
with the error message
"Warning: Displaying real part of complex input", and
"??? Function 'real' is not defined for values of class 'cell'."
can anyone pls tell me why?thanks!!

| Hi,
I think file_list is a cell array of string. Am I right ?
So try :
filename = file_list{index_selected(i)};
