Like this?
data = dlmread('exportfilecst4.txt');
x = data(:,1);
y = data(:,2);
z = data(:,6);
figure
surf(reshape(x,31,[]),reshape(y,31,[]),reshape(z,31,[]))

When you are editing something here on MATLAB Answers, if you look between the edit box and the Cancel / Submit line, then there is a checkbox for "Follow activity on this question" and that is followed on the same line by "(change notification settings)". You can click on "notification settings" to access the Notification Preferences window.
The first preference you can set on that page is for
