how to compute number of element in matrix ?

if i have this matrix

 A = [ 1 3 2 0
       2 2 1 0
       1 2 1 1 ] 

 first i want to compute x which mean the sum of element in each row like this 

x = [ 6
      5
      5 ] 

 second i want to compute y which mean the number of element non zero in each row like this 

 y = [ 3
       3
       4 ]

A = [ 1 3 2 0
     2 2 1 0
     1 2 1 1 ] 
 a=sum(A,2)
 b=sum(A~=0,2)
