MATLAB: How to remove zero sum row from matrix

Question

A=[1 2 3 4 5 6;
   0 0 1 1 0 1;
   0 0 1 0 1 0]

Sum of second and third row if equal to zero, then in new matrix that column is to be excluded. So, the result shall be

A=[3 4 5 6;
   1 1 0 1;
   1 0 1 0]

Answer 1

colToRemove = sum(A(2:end,:))==0;
A(:,colToRemove) = [];
