I have generated a 4D matrix (x,y,z,t) which stores the temperature value for the corresponding x,y,z coordinates at 't' timestep. This is as a result of transient heat transfer analysis. Is there a way I can animate the plot for temperature in 3D?

If not, can I show the animation of temperature with time for any chosen z?

Just use pause and for loop

maxt = max(t);
mint = min(t);
N = 100;
cmap = jet(N);                % generate N colors for temperature
plot3(x,y,z)
hold on
for i = 1:length(x)
    itemp = round((t(i)-mint)/(maxt-mint)*(N-1))+1;
    h = plot3(x(i),y(i),z(i),'.','color',cmap(itemp,:));
    pause(0.1)
    delete(h)
end
hold off
