Generate animation from graph

Question

I am generating a graph with the following command:

X = linspace(0, 1, n);
Y = linspace(0, 1, n);
surf(X,Y,B(:,:));

But how to make it generate an animation of the graphic? I know nothing of MATLAB...

Answer 1

It is relatively simple to generate animations in Matlab, you need to create a for and with each step generate the desired output, call the function getframe immediately after the function responsible for generating the graph, this function acts as a print screen in the chart window, place each frame in a position and finally call the function movie to execute the captured frames, the information you have passed so far is not sufficient to understand what is the expected output of your algorithm, or you expect movement to occur in your linearly created vectors(X,Y) or that they remain fixed and that only animation occurs in B, you need to define this, a pseudo example of the steps explained above:

for j = 1:50
     %A cada passo um surf diferente deve ser gerado de acordo com a sua necessidade 
     surf(X,Y,B(:,:));
     %captura os frames
     anima(j) = getframe;
end
%executa a animação no matlab
movie(anima,50)

Run this example to familiarize yourself and see the result:

Z = peaks;
figure('Renderer','zbuffer');
for j = 1:20
    surf(sin(2*pi*j/20)*Z,Z)
    F(j) = getframe;
end
movie(F,20)
