Reshape a matrix into vector form and then again convert the array into previous dimensions matrix

Suppose I have a matrix of size mxn and i want to convert it into an array and perform some operations on it and then later i want to regain the original matrix of same size mxn from that array

for e.g

    A=[55 53 52 ;54 53 52 ;56 56 54];

    array = 55    53    52    54    53    52    56    56    54

and then this array

    array = 55    53    52    54    53    52    56    56    54

matrix

    A=[55 53 52 ;54 53 52 ;56 56 54];

array = reshape(A.', 1, []) 

A = reshape(array, n, m).'

Notice this is not m, n.

what is n, and m here?

You started by saying "Suppose I have a matrix of size mxn"
