How can I specify thread tasks?

I have to loop through all the n choose m combinations of the numbers 1:n. I have this algorithm:
vals = 1:m;
hasNext = true;
while(hasNext)
%do the task here
for M = m:-1:1
if vals(M)<n-m+M
vals(M) = vals(M)+1;
for MM = (M+1):m
vals(MM) = vals(M) + MM - M;
end
break;
end
if M==1
hasNext = false;
end
end
end
obviously parfor is not ideal here. I want to split the computation to multiple threads by splitting up the task to different sections and run that on different cores. LD;DR: Is it possible to do something like:
thread1.check(first part);
thread2.check(second part);
...

You might want to use parfeval()

Wow, thanks! Meanwhile I was able to generate all the combinations and then do the parfor on that. But this is better as we don't have to use all the memory for the values.
