Matrix to vector

[shm83]

Good afternoon.

I wonder if there is a way (command) to put all the elements of a matrix (row by row) into a vector without using a loop.

Example:
Matrix A = [2 3
4 5]
Vector B = [2 3 4 5]

Thanks in advance

Use the @vech function on the transpose of the matrix.

thank you Gareth.
I used @vec because I needed the complete data. @vech is only for the upper triangle of a squared matrix, but I could have not reached to that without your help. :)
