Returning matrix value back from Single-Indexing-colon matrix

If I have a matrix 3X5: A =

     1     2     3     4     5
     4     3     2     1     5
     7     5     3     2     5
and I want to convert it into single-indx matrix
 d=A(:)
d =

     1
     4
     7
     2
     3
     5
     3
     2
     3
     4
     1
     2
     5
     5
     5

Q: is there a simple way to return the matrix 'A' again from 'd' to its original 3X5 again? Why I am doing that? because using this way in my code, I am saving lots of time of calculations.
