I have a list (matrix) that looks like this
x={{1,0},{2.5, .5},{3,0},{0,2}}
Now I want to eliminate those vectors that have zero for the second
case. That is, I want to get
{{2.5, .5},{0,2}}.
Is there a quick way of doing this?
I tried to apply Select to this but could not get it to work.
Thanks for your help.
