struct_filter

SYNOPSIS
  Apply a filter to a struct

USAGE
  struct_filter(Struct_Type s, Int_Type i)

DESCRIPTION
  This function applies the filter `i' to the fields of a structure
  by performing the operation

s.field = s.field[i];

on each array field of the structure.  Scalar fields will not be modified.

The `dim' qualifier may be used to filter on a specific array
  dimension.  For example, consider the structure

s = struct { a = Int_Type[10], b = Int_Type[10,20] };

Then

struct_filter (s, i; dim=0);

would produce the same result as

s.a = s.a[i];
    s.b = s.b[i,*];

NOTES
  By default this function modifies the fields of the structure passed
  to it.  Sometimes it is desirable to create a new structure and
  leave the old one untouched.  This may be achieved using the
  `copy' qualifier, e.g.,

filtered_s = struct_filter (s, i; copy);
