Hello, 

I am trying to run a for loop in the get function and keep encountering problems. Thanks in advance for help and suggestions to resolve this problem. I created a GUI and have three editable textboxs taged text1, text2, and text3 and a push button taged pushbutton1. The code below is in pushbutton1 function. Please find code and error message below.

code: 

for b= 1:3
    target_temp_string(b) = get(handles.textb, 'String');
end

for c= 1:3
    target_temp_string(c)
end

error message: 

??? Error using ==> struct2handle

??? Error using ==> test('text3_CreateFcn',gcbo,[],guidata(gcbo))

Instead of get(handles.textb, 'String');
try:
get(handles.(sprintf('text%d',b)),'String');
