Creating a vector out of a matrix

I have a 10x10 matrix (called A) and I'd like to make a 1x100 vector (called B) out of the rows of A. And I'm not sure if there is a fast way to program this in MATLAB.

Transpose A and read out the elements linearly:

At = A.';       %' transpose to read across A
B = At(:).';    %' (:) creates column vector, transpose with .'

Short example:

>> A=magic(3)
A =
     8     1     6
     3     5     7
     4     9     2
>> At = A.'; 
>> B = At(:).'
B =
     8     1     6     3     5     7     4     9     2
