MATLAB Nested Loop

MATLAB also allows using one loop inside another loops.

The syntax for the nested for loop statement in MATLAB is as follows:

for m = 1:j 
for n = 1:k 
 <statements>;

       end 
end

The syntax for the nested while loop statement in MATLAB is as follows:

while <expression1>
 while <expression2>
      <statements>
      end
end

Example:

We can use the nested for loop to display all the prime numbers from 1 to 100.

for i=2:100
         for j=2:100
               if(~mod(i, j))
                    break; % if factor found, not prime
              end
        end
        if(j > (i/j))
                  fprintf('%d is prime\n', i);
        end
end 

Output:

2 is prime
3 is prime
5 is prime
7 is prime
11 is prime
13 is prime
17 is prime
19 is prime
23 is prime
29 is prime
31 is prime
37 is prime
41 is prime
43 is prime
47 is prime
53 is prime
59 is prime
61 is prime
67 is prime
71 is prime
73 is prime
79 is prime
83 is prime
89 is prime
97 is prime
