I have created a GUI using GUIDE named MainGui,
this gui will process data and give results to other gui named outputGui created also with guide,
the data processed comes from an inputGuis that process some inputs and generate the data to be sent to MainGui , processing and sending data to MainGui happens when I push a button in an inputGui then inputGui will be closed
my question is: is there any way to pass data from one gui to another knowing that the guis are in separate figures and have separate .m files and they are not programmatic guis
thanks in advance

I good way to do it is declaring global variables. In case you need to "transfer" a whole lot of variables, it is more practical to declare a global struct ,how? Right after the declaration of any function in any of your GUIs, define:
global global_struct
( for example: function your_fun(inputs) global global_struct ... ... )
where global_struct can be renamed as you please. To save a variable:
global_struct.var1 = whatever; % for example: global_struct.var1 = srt2double(get(handles.box1,'String')); )
global_struct.var2 = anything_you_want;
The variables will be accessible for any function/GUI and can be modify too.

thanks David, I have one question about the use of global variables, if the input GUI set globalstruct.var1=value1; and close it self by the command close, do the MainGui still can see the variable globalstruct.var1, or I should not close the input Gui but just hide it and how to hide it.
thanks in advance

If you want to get way from the use of global variables you try guidata(). A quick search of the forums came up with this link https://www.mathworks.com/matlabcentral/newsreader/view_thread/254309. which discusses how they were able to pass data between the "main" gui and a "sub" gui.
