You cannot interrupt your program from the outside, but you need to check a flag or value inside the program. Usually this is done in loops like this:
tic;
while toc < 900 % 15 minutes
takeYourSnapShot;
end

for example
T0=cputime;
for i=1:1e6
if i==1e6/2
T=cputime-T0, %The time half way through the loop
i,
end
end
