I have a for loop written that evaluates the volume of water in a tank given a new fill rate every hour, one pump that turns on/off based on percentage fill, and one pump that it given on/off per hour. I need to make it run a new iteration every minute, but I am unsure how to do so while still breaking it into hours. Any help is greatly appreciated.

v = s*pC*.01;
a1 = s.*0.85; % tank 85% full
a2 = s.*0.20; % tank 20% full
kt = 1:length(data);
for n = 1:length(kt)
if v>=(a1);
a = 1;
elseif v<=(a2);
a = 0;
else a = 0;
end
if data(n,2) == 1;
b = 1;
else
b = 0;
end
v = v+(data(n,1))-150.*a-100.*b
end

yes, that worked great. I did have another issue, where I was instructed to pump a (first if loop) to turn on at 85% and run until it reaches 20%, but I don't know if that's even possible.

For this, I'm afraid I cannot help. Do you mean "if it's even possible" physically?
By the way, if you are satisfied with the code, I'll post it as answer so the question can be closed.
