Hi,
I need to make a 3D plot that change over time. I have 4 points which doesn't move in x and y, but z is moving through time. For exemple A(1,1,zA) B(1,2,zB) C(2,1,zC) and D(2,2,zD) and I have lots of values for zA, zB, zC, zD over time.
Who can I plot this in Matlab ?
Thank you for your answers.

You can probably adapt this code to do what you want:
[X,Y] = meshgrid(linspace(-5, 5, 50));
fcn = @(x,y,k) k*x.^2 + y.^2;
v = [1:-0.05:-1; -1:0.05:1];
for k1 = 1:2
for k2 = v(k1,:)
surfc(X, Y, fcn(X,Y,k2))
axis([-5 5 -5 5 -30 50])
drawnow
pause(0.1)
end
end

clc; clear all ;
x = rand(4,1) ;
y = rand(4,1) ;
for i = 1:100
z = rand(4,1) ;
plot3(x,y,z) ;
drawnow
pause(0.2)
end
