What's wrong with this code? Can you help me please?
%% Creating Video mp4 from Animation of a graph a point P(x,y) which is variable connected to three fixed point A(6,9),B(20,38),C(49,25).
clc
clear
close all
M=5000;
x=6:1:49; % x domain
y=9:1:38; % y domain
for i=1:length(x)
for j=1:length(y)
clf
L=sqrt((x(i)-6)^2+(y(j)-9)^2)+sqrt((x(i)-20)^2+(y(j)-38)^2)+sqrt((x(i)-49)^2+(y(j)-25)^2);
if L<M
M=L;
a=x(i);
b=y(j);
p = [6 20 49]; % x coordinates of three fixed points A, B, and C.
q = [9 38 25]; % y coordinates of three fixed points A, B, and C.
hold on;
grid on
title('Steiner minimal tree')
for n = 1:length(p)
plot([p(n) a],[q(n) b],'color',[0 0 1]);
myChar = char(64+n);
text(p(n)+1,q(n),myChar);
end
plot(p,q,'o','markerfacecolor','k','markeredgecolor','none', ...
'markersize',4);
plot(a,b,'o','markerfacecolor','r','markeredgecolor','none', ...
'markersize',8);
text(a+0.5,b+0.75,'P');
drawnow;
pause = .01;
F(i,j)= getframe(gcf);
end
end
end
mywriter = videowriter('Steiner minimal tree','MPEG-4');
mywriter.framerate = 60;
open(mywriter);
writevideo(mywriter,F);
close(mywriter);
Whwn I run this file command window shows
Cannot find an exact (case-sensitive) match for 'videowriter'
The closest match is: VideoWriter in F:\Matlab Alx\toolbox\matlab\audiovideo\@VideoWriter\VideoWriter.m
Error in animate_figure (line 37)
mywriter = videowriter('Steiner minimal tree','MPEG-4');

VideoWriter % correct one you have give videowriter(not case sensitive)
