%DDEUNADV Release advisory link.
% DDEUNADV releases the advisory link between MATLAB and the server
% application, established by an earlier DDEADV call. The channel,
% item, and format must be the same as those specified in the call
% to DDEADV that initiated the link. If you include the timeout
% argument but accept the default format, you must specify format
% as an empty matrix.
%
% rc = DDEUNADV(channel,item,format,timeout)
%
% rc Return code: 0 indicates failure, 1 indicates success.
% channel Conversation channel from DDEINIT.
% item String specifying the DDE item name associated with
% the advisory link.
% format (optional) Scalar specifying the format of the data
% requested. The value indicates the Windows clipboard format to
% use for the data transfer. Use '1' for CF_TEXT transfer or
% the value returned from CLIPFORM to select binary transfer.
% The default format is CF_TEXT.
% timeout (optional) Scalar specifying the time-out limit for this
% operation. Timeout is specified in milliseconds.
% (1000 milliseconds = 1 second).
% The default value of timeout is three seconds.
%
% For example,
% Release the hot link established in the ddeadv example
% rc = ddeunadv(channel, 'r1c1:r5c5');
%
% Release a hot link with default format and value for timeout
% rc = ddeunadv(chan, 'r1c1:r5c5',[],6000);
