I am trying to convert a matrix into one column vector. For example, if I have A=[1 2 3;3 4 5;0 2 5] and I want to transpose all the rows and combine them to get one single column vector like B=[1;2;3;3;4;5;0;2;5]. Anyone has an idea on how to do it, please help me.

B = reshape(A',[],1);

@James, Thanks for this code. It's working perfectly.
The above traverses the matrix column wise and converts it into a 1D vector. Little extension to this problem, when this traversal is row wise in the matrix and then it is converterd to the vector. What should be the code for it?
