MATLAB: While loop: value increases, break if not.

for loopif statementvariablewhile loop

Is it possible to use while loop that checks if the variable is increasing each step and break if not?

Or I have to use for loop, something like this:

for i=2:N
   if x(i-1)>x(i)
   x(i)=0;
   end
end

You could use a while loop instead to run until a conditions is met, and it'll automatically break.

i = 2;
while x(i) <= x(i-1)
  i = i+1;
end

Or, you could use a break statement.

for i = 2:N
  if x(i) > x(i-1)
    break
  end
end

In nested loops, break exits from the innermost loop only

MATLAB: If loop: What’s going wrong

These are the relevant parts of the code:

loopcount = 0;
...
if TotalEnrolledNew < 10000;
    ...
    ... irrelevant loop here
    ...
    loopcount = loopcount + 1
else
   ...
   ... another irrelevant loop here
   ...
end

As you can see all loops are totally irrelevant to your loopcount variable: it is not incremented in any loop because it is not inside any loop.

It is not clear what you expect loopcount to do, or why you think it has anything to do with loops.

"The idea is quite blatant, to follow the first set of rules until TotalEnrollmentNew is greater than 10000, then follow the new set of rules using TotalEnrolledNew in its first iteration."

You don't change TotalEnrolledNew inside any loop, so it is not clear how this description corresponds to your code. If TotalEnrollmentNew should be changing "until" some condition then you need to be defining/updating its value inside some loop of some kind, perhaps something like this:

TotalEnrollmentNew = ...
...
while TotalEnrolledNew < 10000;
    ...
    TotalEnrollmentNew = ...
end
...
... move on to the next "set of rules":
while ...
    ...
end
