I have a 14x14x221 matrix, A, where the Z component is time. I need to make a colored animation of how the X and Y components change with time. The code I have written now just creates a new figure for each iteration of the loop so it produces 221 figures that appear after closing out of the previous figure.

Q=length(A);
for i=1:Q
    W=A(:,:,Q);
    pcolor(W);
    drawnow
    pause(0.3)
end

在 MATLAB Online 中打开

Q = size(A,3);
W = A(:,:,1);
h = pcolor(W);
drawnow();
pause(0.3);
for K = 2 : Q
    W = A(:,:,K);
    set(h, 'CData', W);
    drawnow();
    pause(0.3);
end
