Thread Subject: Deleting rows

Assume we have a matrix,

a =[8 3;9 3;7 2;4 2;5 1;10 1]

After some operations a(:,2)=a(:,2)-1 and when there are numbers in the second column equal to 0, I wish to delete the complete row. Is there a faster way to do it than the following?

Now a = [8 2;9 2;7 1;4 1;5 0;10 0]

b=find(a(:,2)==0);
a(b,:)=[];

Thanks!

You don't need the find function for this:
a(a(:,2)==0,:)=[];
