回答： Sudheer Bhimireddy 2020-8-5

The code below creates a movie which shows the growth of a droplet. This is done by reading a text file that contains 3 columns The first 2 columns are the droplet location i.e. x and y coordinates and the third columns in the droplet radius. In the current format I am able to plot the droplet but instead of increasing in its size, it travels up the 'r'. Is there anyway to allow the droplet to remain on the x,y plane but increase in size using the 'r' value?

clear
clc
close all
%% STEP ONE: LOAD DATA
a = '.txt';
%% STEP TWO: DRAW/RENDER SCENARIO
for i = 1:20
    
    clf
    
    str = int2str(i);
    stp = strcat(str,a);
    c = load(stp, 'w+');
    s = size(c)
    s1 = s(1,1)
    s2 = s(1,2)
    
    
    for ii = 1:s1
        x(ii,1) = c(ii,1);          % x-coordinate
        y(ii,1) = c(ii,2);          % y-coordinate
        r(ii,1) = c(ii,3);          % radius
        
        
    end
    
      plot3(x,y,r,'go')
      title (['Droplet size at t = ',num2str(i),' seconds'])
      
       drawnow
end
