Deleting every row with a zero in the first column, except the first row

5 views (last 30 days)
I have the following Matrix A
A = [0 0; 2 5; 3 6; 7 0; 0 5; 0 3]
I'd like to delete every row that has a 0 in the first column, except the first one.
So thats my code so far
A(all(A(2:end,1)==0,2),:)=[];
it works just as I'd like it to, but it always deletes the 4th row and gives me instead the last one.
Thanks for any help

Try this:
A([false;~A(2:end,1)],:) = []
