I would like to run a .m file by using pushbutton in GUI, the .m file output is an array which is not loaded in the workspace. Is there anyway to execute .m file using GUI or to load the output.

Thanks, Arif

Is your .m file a function or a script? You need to understand the difference. Functions and Scripts.

If it is a function, you can use output argument to pass in the data. If it is a script, you can run the .m file directly with the GUI function callback to set up the data, although this approach is not recommended.

Thanks for reply.But I am facing the same problem-

I want to make a GUI which has a push button and in the workspace there is a Matrix A.I want that whenever I click on the push button it will take the Matrix A manipulate matrix according to the code and then output the matrix on the workspace.But it is not happening because whenever I click the push button code run but new matrix is not displaying on the workspace.Could you please help me for that.I am sending you the code which I have written in push button function-

% --- Executes on button press in pushbutton2.

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(evalin('base','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

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';

Final_Array{1,1}='voltage';

Final_Array{1,2}='Time';

Final_Array{1,3}='S.No';

for(x=1:A(l))

string=strcat(string,modified_data(x));

end

Final_Array{2,1}=string;

string='0';

for(x=A(l):A(2))

string=strcat(string,modified_data(x));

end

Final_Array{2,2}=string;

string='0';

for(x=A(2):A(3))

string=strcat(string,modified_data(x));

end

Final_Array{2,3}=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{2+(l-1)/3,1}=string;

else if(rem(l,3)==2)

Final_Array{2+(l-2)/3,2}=string;

else Final_Array{2+(l-3)/3,3}=string;

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'))

Thanks

If you want to make Final_Array available in base workspace, run this at the end of the function.

assignin('base','Final_Array',Final_Array);
