My Code:
======================================…
>>
disp('input a pair of natural numbers, N and M with M>N');
N=input('N=');
M=input('M=');
for j=0:(M-N)
Prime=1;
for i=2:((N+j)/2)
if mod((N+j),i)==0
Prime=0;
break
end
end
if Prime==1
disp('This is a Prime number');
else disp('Not Prime');
end
end
