Matlab finds a prime number that is greater than a given integer and follows this integer

Problem description ： Find an integer greater than the given value （ Greater than required 30） And then the prime of this integer , And output as program value .

Go straight to the code ：

clc;clear;
n=input(' Please enter n:');
for i=n+1:1e+4
    for j=2:i
        if(rem(i,j)==0&&i~=j)
            break;
        elseif(j==i)
            fprintf(" Followed by Prime %d\n",i);
            return ;// It's the following , Not all ！
        end
    end
end

Be careful ：return It can't be less , Or you can try .
