Hello,

You can make use of uiimage to display images in the GUI.

I am not sure, whether you are looking for this. I just read three images and display them for a duration of 1second and show the other image based on the value in the vectorInput.I have a one to one mapping between vectorInput values 0,1,2 with img0,img1 and img2.

img0 = imread('membrane.png');
img1 = imread('peppers.png');
img2 = imread('football.jpg');
vectorInput = [0 0 1 2 2 0];
f= uifigure();
img =uiimage(f);
for i=1:length(vectorInput)
    if(vectorInput(i) == 0)
        img.ImageSource  = img0;
    elseif(vectorInput(i) == 1)
        img.ImageSource  = img1;
    else
        img.ImageSource  = img2;       
    end
    pause(1);%Holding image for 1 second
end

Proyecto.zip

Hi I've tested your code and It works but the vector I have has 34470 elements so I need the loop to be a little bit faster. It only has 0,1, 2 and 3 values and what I need is: when I have a 0 I need to display an arm image(brazo22) in repose, when is 1 I need to display an arm image in flexion(brazo11) ,when is 2 I need to display an arm image in extension (brazo33) and when it has a 3 I need to display the same image as when It's in repose(brazo22). I´ll attach a zip that contains the gui(poyecto.fig) the function of the gui with your code (proyecto.m), the images of the arm, another function that is the function where I extracted the code for the gui(SolucionP2_eje2.m) and a data archive(EMG 2 channel Wrist Flex_Ext_Raw.mat). In both of the .m archives is a vector called "salida" that is the vector with the 4 values. A brief summary of what I need is: I have a data archive that I have processed and then make a vector "salida" for the values in the previous data. Now I need to make a gui for that 3 values to display an image deppend on the value. The problem is that I need the loop to last 23.16 seconds but the vector "salida" has 34470 elements. Do you have any idea to make this possible? Thank you for your answer.
