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.
