i want to suppress any output that if might give if it is false.
for example, i want to prune a list so that all ordered pairs {x,y} fulfill xy>5
here is what i did:
f{x_,y_}:=x*y
table[If[f[x]>5,x],{x,listtobepruned}]
the above works, just leaves a Null whenever it is false.
is there a way to get it to just "move on" instead of printing all of these Nulls?
also, is there a way to do find and replace in a formula:
ex. list = {{{1,2},{3,4}},{{5,6},{7,8}}}
is there a way to do
{{ = {
}} = }
or something like that so i end up with
{{1,2},{3,4},{5,6},{7,8}}
thanks
