Converting matrix of rows to one row

I have to convert a matrix to a one row vector composed of all the rows of the original matrix. How can I do this? Thanks

A = rand(3) ;  % A 3x3 matrix
A = A' ;
iwant = A(:)' ;  % convert to vector

I have 6 images. In each, I have identified a number of different special points on which to extract the attributes. (Because of the different cell)

In the first image I have 15 matrices, 3 x 3. And so there are the number of special points in each matrix image.

First, I want to transform the individual matrices of each cell into vectors. Then paste them into their own rows.

I know a simple matrix can be transformed into a vector with (:). But I can't work with that many cells.
