help needed for a grep in a multidimensional struct array

[Gianluca Antonelli]

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.
