Created by Loris Chavée

Solve Later

Considering a matrix A, sort the prime numbers of each row in ascending order. For exemple:
      input A=[5 8 2 4;
               1 11 1 5]
output B=[2 8 5 4;
          1 5 1 11]
You don't have to sort the other numbers, just the prime numbers. Enjoy!

Not sure why the problem title says "3x3 matrix", then uses non-3x3 matrices in the example and test suite. Considering rewording for clarity.
