Suppose I have 8 variables and I want to run an If function if at least two of those variables are equal to one. All variables are real numbers and should be converted to integers meaning 1.8 or 1.2 should be rounded to 1. How can I implement this as a function?
x1=22, x2=3.3, x3=1.2 x4=1 x5=1.7 x6=44 x7=6 x8=4

It is time to learn how to use a vector instead of numbered variables.
Regardless, 1.8 does not round to 1. Floor or fix might be a better choice of words, IF that is your intention.

Presuming you have followed John's good advice and placed your eight values in a single vector, which I will call v, do this:
t = sum(round(v)==1)>=2; % Or perhaps you meant 'floor' instead of 'round'
The variable t can be used in the if statement.

Completely agree with John. But just in case:
if length(find(fix([x1 x2 x3 x4 x5 x6 x7 x8])==1))>=2
...
condition
...
end
