What’s New in MATLAB R2022a? – Nick Higham

The append possibility of the exportgraphics operate now helps the GIF format, enabling one to create animated GIFs (beforehand solely multipage PDF information had been supported). The important thing command is exportgraphics(gca,file_name,"Append",true). There are different methods of making animated GIFs in MATLAB, however this one is especially straightforward. Right here is an instance M-file (primarily based on cheb3plot in MATLAB Information) with its output beneath.

%CHEB_GIF  Animated GIF of Chebyshev polynomials.
%   Based mostly on cheb3plot in MATLAB Information.
x = linspace(-1,1,1500)';
p = 49
Y = ones(size(x),p);

Y(:,2) = x;
for ok = 3:p
  Y(:,ok) = 2*x.*Y(:,k-1) - Y(:,k-2);
finish

delete cheby_animated.gif
a = get(groot,'defaultAxesColorOrder'); m = size(a);

for j = 1:p-1 % size(ok)
    plot(x,Y(:,j),'LineWidth',1.5,'shade',a(1+mod(j-1,m),:));
    xlim([-1 1]), ylim([-1 1])  % Should freeze axes.
    title(sprintf('%2.0f', j),'FontWeight','regular')
    exportgraphics(gca,"cheby_animated.gif","Append",true)
