% function M = setr(recordvar, fieldname, fieldvar)
%
% Creates record variables and creates and changes the contents of fields.
% Matlab 5 compatibility version.
%
% M		RecVarT
% recordvar	RecVarT or []
% fieldname	StringT
% fieldvar	Any type
%
% Ex:
%     A = setr(A, 'frequency', 2800);	
%     % Sets the field 'frequency' to the value 2800 in the record variable 'A'.
%
% If 'recordvar' is not an record variable an error message is issued.
% To create a new record variable use 'recordvar' = [].
