How do I convert the (n, n) matrix to a (nxn,1) vector? Any suggestions?

It would be of great help if someone can give some suggestions, or the MATLAB command which does this operation.

vertcat(A,A)

Or simply

a=a(:)

Thank you @Torsten :)

Thank you for your answer. What I mean by (n*n,1) is stacking of same matrix and later considering it as an array of data in 1 column.

[madhan ravi]

see the edited code it gives what you want

[Dhananjay Mishra]

Let A = [1 2; 3 4]. The output I need should look something like A = [1 2; 3 4; 1 2; 3 4; 1 2; 3 4; 1 2; 3 4]. The number of matrix to be stacked is the numeric multiplication of initial matrix dimensions

A = [1 2; 3 4];
A = repmat(A,size(A,1)^2,1)
