Hello everyone,

I am trying to navigate over matrix and show this action as visual step-by-step. Actually, I created scheme as an image that I want to work on it but I want to use another format except image because, working over an image is so hard. For instance, I labored while I was trying to show colored box on matrix due to that I have to care the pixel detail. I have attached my scheme and code below. While running the code, you should give 2 inputs which is between 0 to outs (10 for default).

Please suggest me another way to show colored boxe moves over matrix.

outs=10;
colors=rand(outs,3)*255;
res=50;
borderThickness=5;
whSize=(res+borderThickness)*outs;
chart=uint8(ones(whSize,whSize,3)*255);
for i=1:outs+1
    fIndex=(res+borderThickness)*(i-1)+1;
    LIndex=fIndex+borderThickness-1;
    chart(fIndex:LIndex,1:end,1:end)=0; 
    if(i==outs)

Yes. By writing "move", I wanted to mean exactly that you write. Actually, I am doing like your method but this way is not efficient method in my oppinion. I wonder is there another method better than struggling image pixels.

Sx = 16; Sy = 16;
vimg = cat(3, zeros(Sy, Sx), ones(Sy, Sx), zeros(Sy, Sx));  %a green object
vhand = image(vimg);
for ....
        new_x = ...;
        new_y = ...;
        set(vhand, 'XData', [new_x, new_x+Sx-1], 'YData', [new_y, new_y+Sy-1]);
        drawnow();
end
