How might I terminate a for loop based on an if statement?

I'm quite new to MATLAB and I believe this is a fairly simple question but I am hoping someone could help me with how to terminate this for loop when the condition of the if statement inside the loop becomes true? i.e. if a = [2,2,3,2] and b = [2,1,1,1] how might I be able to go about terminating the loop early so that numMatch = 1 when the loop has ended instead of having numMatch = 3?

a = [2,2,3,2]
b = [2,1,1,1];
numMatch = 0;

for (n = 1:4)
    if (guess(1) == answer(n))
        numMatch = numMatch + 1;
    end
end
