[Maxima-discuss] grep, filter, select, remove-if-not in maxima?

[Alexander P. <po...@gm...>]

Hi everyone!

Can you, please, point me to correct Maxima idiom to select elements of 
the list, satysfying certain criterion?
The following variants:
1. grep (a la Perl)
2. filter (a la Python)
3. select (a la Mathematica)
4. remove-if-not (a la Common Lisp)
do not work, and my imagination is exhausted =). Of course, this could 
be done with going to lisp-level and doing remove-if-not,
but it is annoying to do that all the time...

Yours sincerely,
Alexandr Popolitov
