Can anyone help me with index in position 2 exceeds array bounds (must not exceed 1). in line 39. My project is offside detection in football but i don't even know what offside exactly is i don't know is my code gonna work properly :( im stuck

    for j=1:c
        if (h(i,j)>=0.01 && h(i,j)<=0.99)
            out(i,j)=255;
        else
