Minimum value of loop

if i have loop, for example

>> for i=1:3

a=i+2

end

the MATLAB will give me

a= 3,4,5

The question is: how to make matlab give me only the minimum value between those? which is 3

because i have many solutions and i want only the minimum one

>> N = 3;
>> a = Inf;
>> for k = 1:N, a = min(a,k+2); end
>> a
a =  3
