You can use 2d arrays in matrix storage. Usually, we may use them nicely while multiplying 2 matrixes, adding and subtracting from each other. So it is nice to use 2d arrays in matrix operations. Make, for ex. i rows, j columns of the matrixes. I personally used when studying matrix mulpitplications in visual basic in visual studio.
