deleting entries across all fields of a structure

I have a datastructure docMetaS =

           DOCUMENT_ID: [184899x1 int32]
    DOCUMENT_PUBLISHER: [184899x1 int32]
            LIST_PRICE: [184899x1 int32]
      PRIMARY_CATEGORY: {184899x1 cell}
                 PAGES: [184899x1 int32]

index = [80:100]

I would the elements with indices from 80 to 100 for all the fields in the structure.

I know it is possible to do using docMetaS.DOCUMENT_ID(index) =[];

and so on for all the four elements.

Is there a elegant way to do this in one or two statements?

Thanks,

Sankar

An example:

% Create a structure with multiple fields.
S.a = rand(1,100);
S.b = rand(1,100);
S.c = rand(1,100);
S.d = cellfun(@(x) rand,cell(1,100),'Un',0);
S  % Show the structure, then delete some of it:
S = structfun(@(x) x([1:79 90:100]),S,'Un',0);
S  % Show the reduces structure.

Hi Matt Fig,

Excellent Answer. This solves my problem. I did not know that structfunc is this powerful.

Thanks,
