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)
