How to display a .mat file in a axes in GUI. I have a out.mat file obtained from another GUI operation . I want to open this file in a new GUI that has an axes field to it . When I click a pushbutton called image I must be able to show that out.mat on the axes field. Any help on how to do it.

A mat file contains variables. How those variables are "displayed" depends on what kind of variable is in the .mat file. For example with images you can use imshow() and for vectors you can use plot(). You forgot to attach your mat file, so there's not much we can do. I'll check back later for it.

在 MATLAB Online 中打开

file_struct = load('out.mat');
embedded_image = file_struct.embedded_image;
imshow(handles.AXES_TO_DISPLAY_INTO, embedded_image);

Note: the out.mat file has a figure stored inside it, and that figure will become visible... probably confusing people. You can make it invisible by

file_struct.handles.figure1.Visible = 'off';

Correction:

embededimage = file_struct.embededimage;

Thanks for the help

how to select a .mat file by specifing its path and type and then display it on the axes. If the .mat file is user selected what must be the parameters inside imshow .

[filename, pathname] = uigetfile('*.mat', 'Pick an M-file');

if isequal(filename,0) || isequal(pathname,0)

disp('User pressed cancel');

end

axes(handles.axes5);
