I have the following loop that plots and re-plots data in MATLAB using thesurf() function. How do I get the plot to update while the values are changing and how do I animate it?
s = 1;
timerID = tic;
while true
if(toc(timerID) > 25)
break;
end
for i=1: 5
removeChannel(session, 7)
addAnalogInputChannel(session,'cDAQ1Mod8',['ai' num2str(i+15)],'Voltage');
for j=1: 5
measurements(6-j,6-i) = abs(session.inputSingleScan) - abs(base);
end
end
surf(interp2(flipud(abs(measurements)),4));
view(0, 90);
colorbar;
pause(0.05)
s = s+1;
end

I am not certain exactly what you want to do, and I cannot run your code to test this with it.
See if this example offers some idea on how to do what you want:
[X,Y] = meshgrid(linspace(-15, 15, 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([-15 15 -15 15 -300 500])
drawnow
pause(0.1)
end
end
