I have a line of code that generates a stick figure in 2D:

close all; clear all; clc  
% Head
syms t
x(t) = sin(t);
y(t) = cos(t);
fplot(x,y+4, 'b', 'LineWidth',2) 
axis([-10 10 -10 10])
hold on
grid on
% Stomach
fplot(2*x,2*y-2,'k','LineWidth',2)
% Body
syms t
x(t) = sym(0);
y(t) = t;
fplot(x,y,[-4 3], 'b', 'LineWidth',2) 
% Legs
syms x
fplot(2*x-4, [-2 0],'b','LineWidth',2)
fplot(-2*x-4,[0 2],'b','LineWidth',2)
% Arms
fplot(sym(0), [-2 2],'b','LineWidth',2);
% Save Image
filename = 'Stickman.gif';

I am attempting to generate an animation (and save) utilizing the functions getframe and movie to display the "stomach" expanding.

Is there a simple way in which to do this?

Thank you

在 MATLAB Online 中打开

Use for loop and pause

t = linspace(0,2*pi);
x = cos(t);
y = sin(t);
axis([-10 10 -10 10])
hold on
for i = 1:10
    h = plot(i*x,i*y);
    pause(0.5)
    delete(h)
end
hold off
