Re: Automatically Combining Structures

[Etienne Grossmann]

  Hi Bill,

I use this.

  Hth,

  Etienne

======================================================================
## z = struct_merge (a,...)     - Merge any number of structs
##
## a,... : structs : The structs that will be merged.
##
## z     : struct  : z has all the fields of a,... If many arguments
##have
##                   the same field, the value of the last is used.
function a = struct_merge (a,varargin)

va_arg_cnt = 1;
nargin = nargin();
while --nargin

  b = nth (varargin, va_arg_cnt++);
  ## s = ¨;
  for [val, key] = b
    ## s = [s,sprintf (ä.%s=b.%s;",key,key)];
    a.(key) = val;
  end
  ## eval (s);
