I got an error in using this code in GUI
??? Error while evaluating uicontrol Callback
??? Undefined function or variable 'data_to_be_exported'.
Error in ==> MAIN_GUI>pushbutton2_Callback at 112
modified_data=cell2mat(data_to_be_exported);
Error in ==> gui_mainfcn at 96
feval(varargin{:});
Error in ==> MAIN_GUI at 42
gui_mainfcn(gui_State, varargin{:});
Error in ==> @(hObject,eventdata)MAIN_GUI('pushbutton2_Callback',hObject,eventdata,guidata(hObject))
??? Error while evaluating uicontrol Callback
ERROR IS-
CODE is-
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton2 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
modified_data=cell2mat(data_to_be_exported);
i=1;n=1;A=zeros(size(modified_data));d=1;
for (n=1:size(modified_data,2))
if(modified_data(1,n)==',')
A(1,i)=n;i=i+1;
n=n+1;
else n=n+1;
end
end
p=size(modified_data,2);
for(m=1:p)
if(A(1,m))>0
p=p+1;
else end
end
size_of_the_finalarray=p-m;
l=1;
string='0';
for(x=1:A(l))
string=strcat(string,modified_data(x));
end
Final_Array{1,1}=string;
string='0';
for(x=A(l):A(2))
string=strcat(string,modified_data(x));
end
Final_Array{1,2}=string;
string='0';
for(x=A(2):A(3))
string=strcat(string,modified_data(x));
end
Final_Array{1,3}=string;
for(l=4:size_of_the_finalarray)
string='0';
for(x=A(l-1):A(l))
string=strcat(string,modified_data(x));
end
if(rem(l,3)==1)
Final_Array{1+(l-1)/3,1}=string;
else if(rem(l,3)==2)
Final_Array{1+(l-2)/3,2}=string;
else Final_Array{1+(l-3)/3,3}=string;
end
end
end
Final_Array=strrep(Final_Array,'0,',' ');
Final_Array=strrep(Final_Array,'0+',' ');
Final_Array=strrep(Final_Array,'NVDC,',' ');
Final_Array=strrep(Final_Array,'secs,',' ');
Final_Array=strrep(Final_Array,'RDNG#,',' ');
Final_Array=strtrim(Final_Array);
%xlswrite('sample.xls',Final_Array);
xlswrite('test.xls',evalin('base','Final_Array'))
Please suggest some reasons Thanks Arif

Your variable 'data_to_be_exported' is probably in MATLAB 'base' workspace. Your above code 'modified_data=cell2mat(data_to_be_exported);' is in function workspace. Pass in the the data 'data_to_be_exported' through a function call or run the M-script within the function.
