How to get the vector in a matrix (specific location)

I have matrix A (8x4)

A= [ 1  0  0  0  0  0  0  0  
     2  0  0  0  0  0  0  0
     3  0  0  0  0  0  0  0
     4  5  6  7  8  9  10  11]

How can I get vector of B that start from row 4, column 2 till end?

 B= [ 5  6  7  8  9  10   11]

A= [ 1  0  0  0  0  0  0  0  
     2  0  0  0  0  0  0  0
     3  0  0  0  0  0  0  0
     4  5  6  7  8  9  10  11]

B = A(4,2:size(A,2))
