I am a beginner with MATLAB GUIs. I have two GUI figure windows. I want to transfer data from a textbox in the first GUI figure to another second GUI figure & want to use that data in second GUI figure.

Assuming you are using GUIDE to generate your GUIs, you can simply use the tag of the editbox in the first GUI to find it in the second GUI. For example, from within the second GUI callback use:
findall(0,'tag','editbox1tag')

Thanks for your answer. But if you tell me the total code then it will easy for me. My question is I have two gui figure each having a textbox. I want to take the text from the textbox of first figure & then want to transfer it into the textbox in the second gui figure.

I assume you are pushing a button in the second GUI to activate the transfer? If so, put this (or similar) in the callback to the pushbutton:
H = findall(0,'tag','editbox1tag');
set(handles.editbox2tag,'string',get(H,'string'))
Now 'editbox1tag' is the tag to the editbox in the first GUI (which must be unique), and editbox2tag is the tag to the editbox in the second GUI (also unique).

Matt i had the same question.
H = findall(0,'tag','editbox1tag');
set(handles.editbox2tag,'string',get(H,'string'))
Allows me to pass the between GUIs but i can't manipulate them. I think they are string values of the data i want. I've tried using str2num and str2double but i can't perform any operations on the called back values.
Help!!

Here's a tricky non-Guide way to do it. Change the data in the text box and press return to plot the data in figure 2.
% Make figure 1
f1 = figure('Name','Window 1');
% Make figure 2
f2 = figure('Name','Window 2');
% Make the axes in figure 2
a2 = axes('Parent',f2);
% Create a plot function (uses anonymous function syntax)
plotf = @() plot(findobj('Type','axes','Parent',f2),str2num(get(gcbo,'String')));
% Create the edit box
u1 = uicontrol(f1, ...
'Style','edit', ...
'String','[1 2 4 3 5]', ...
'Callback','feval(plotf)');
