Hello everyone :)
I have, say a list of list. Each element is a list of length 3 i.e.
myList={{x1,y1,z1},{x2,y2,z2},...{xN,yN,zN}}
Now, let's say I want to delete from this list the element which have
x=2 and 3 using DeleteCases.
This works :
DeleteCase[myList,{2,_,_}]
DeleteCases[myList,{3,_,_}]
but I would like to use
DeleteCases[myList,{{2,_,_},{3,_,_}}]
and this does not work...
How do I combine multiple patterns in DeleteCases ?
Thanks in advance.
