MATLAB: Plotting users in Matlab

plotting

Hi everyone, I have coded the following figure, in which the users are randomly distributed between the four blocks. I want the users to be only on the street, not inside the building block. Any help will be really appreciated. Thank you guys.

Use the inpolygon function:

Compare the two plots:

Users = 2*rand(20,2);
Bldg = [0.5 0.5; 0.5 1.5; 1.5 1.5; 1.5 0.5; 0.5 0.5];
figure(1)
plot(Bldg(:,1), Bldg(:,2))
hold on
scatter(Users(:,1), Users(:,2), 'xb')
hold off
axis([0  2    0  2])
axis equal square
Street = inpolygon(Users(:,1), Users(:,2), Bldg(:,1), Bldg(:,2));
figure(2)
plot(Bldg(:,1), Bldg(:,2))
hold on
scatter(Users(Street==0,1), Users(Street==0,2), 'xb')
hold off
axis([0  2    0  2])
axis equal square

you can do it like this:

figure('Color', 'white')
UserLocationX = randi(50, 1, 50);
UserLocationY = randi(50, 1, 50);
plot(UserLocationX, UserLocationY, '^', 'MarkerSize', 5, 'LineWidth', 3), hold on
AccessPointX = randi(50, 1, 8);
AccessPointY = randi(50, 1, 8);
plot(AccessPointX, AccessPointY, 'go', 'MarkerSize', 5, 'LineWidth', 4), hold on
BaseStationX = 25;
BaseStationY = 25;
plot(BaseStationX, BaseStationY, 'rs', 'MarkerSize', 5, 'LineWidth', 4), hold on, grid on, grid minor
hleg = legend('User Location', 'Access Point', 'Base Station')
set(hleg, 'Location', 'NorthEastOutside')

MATLAB: Can you have multiple animations running at the same time

"I am wondering if it is possible to have multiple dots travel down the screen at the same time, but have the times offset?"

It is possible but you'll need to change the while-loop. The code below is conceptual and shows how the while loop could change and control the advacement of each ball.

Each ball has its own logical flag. When true, the ball advances. When false, the ball does not advance, For each ball, there needs to be a decision on each iteration within the while-loop and the result of that decision is whether or not the flag is true or false on the next iteration.

hBall1=plot(ballPos1(1),ballPos1(2),'ko','MarkerSize',13,'MarkerFaceColor','y');
% I ADDED ANOTHER BALL HERE:
ballPos7=[1.5,1];
hBall7=plot(ballPos7(1),1,'ko','MarkerSize',13,'MarkerFaceColor','g');
% SET INITIAL FLAG; when true, the ball will move.  
ball1GO = true; 
ball7GO = true; 
while ball1GO || ball7GO
    
    % Test to determine advancement
    if ballPos1(2)<.5
        ball1GO = false; 
    end
    % or ball1GO = ballPos1(2)>=.5; 
    
    if ballPos7(2)<.4
        ball7GO = false; 
    end
    % or ball7GO = ballPos7(2)>=.4; 
    
    % Advance to next position
    if ball1GO
        set(hBall1,'XData', ballPos1(1), 'YData', ballPos1(2));
        ballPos1(2)=ballPos1(2)-.01;
    end
    if ball7GO
        set(hBall7,'XData', ballPos7(1), 'YData', ballPos7(2));
        ballPos7(2)=ballPos7(2)-.01;
    end 
        
    pause(.03)
end

Also, here's no need to call "hold on" so many times. "Hold" is a property of the axes. When it's set to 'on' it stays on until it is turned off.

Your while-loop is a fine method to animate a graphics object but just be aware of this function that can be used as well: an = animatedline(x,y)
