Hi,

I have the following problem.

I have the following variable:

slot  =

30x5x10 struct array with fields:
   modulo
   cdl

I need to find all the indexes for which the field cdl matches a
specific grep command.

I would like to know if is it possible to have a function such as:

out = grep(slot.cdl, "abc")

Any hint?

Thanks in advance,
g.

if slot.cdl contains only single strings
grep(cat(1,slot.cdl(:)),'abc')  //will do the job

explanation:
slot.cdl is a list each list element contains one string.
slot.cdl(:) is the sequence of individual strings
so cat(1,slot.cdl(:)) is equivalent to
cat(1,slot.cdl(1),slot.cdl(2),...,slot.cdl($))
and the result is a vector of strings. so one can apply the regular grep
on it

A more general solution can be to define the  %l_grep function as follow

function k=%l_grep(l,key)
  k=[]
  for i=1:size(l)
    if type(l(i))==10 then
      ki=grep(l(i),key)
      if ki<>[] then k=[k,i],end
    end
  end
endfunction
