source location (X,Y) in a vector in MATLAB is assumed and you want to show the location of the source at each iteration as presented in video below: MATLAB code: %--------------------------------------------------- figure(5); axes(); hold on; img = imread('BACKGOURND.png'); %# Load a sample image hold on; %# Add to the plot image([X1 X2],[Y1 Y2],img); %# Plot the image plot(Xl_t(1,i),Xl_t(2,i),'Xr','MarkerSize',20) %Xl_t --> the mentioned vector for i = 540:1:1000; if (i == 540) pause(15); end %----------------------------- |
