JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the p

function[]=use(x)
%USE  Copies structure fields into named variables in workspace.
%
%   USE STRUCT, where STRUCT is a structure, copies all fields of the
%   form STRUCT.X into variables named X.
%  
%   This is useful for handling multiple datasets with the same
%   variable names.  The structures can be then kept in memory and
%   'mapped' into variables as needed.
%
%   See also MAKE, MATSAVE.
