function return data types about mdsplus HOT 3 CLOSED

Hi -
The matlab functions mds*() are supposed to return standard types. Connect may need fixing. The string returns have been fixed as far as I know. There is one further change to the string code when 2d arrays of strings are referenced. Do you have the current (alpha) /usr/local/mdsplus/matlab ? If so, and you have specific things that are not working correctly, let me know.

Hi,
I have had the same issue reported in this thread, when I used a version 6.1.26 at a Linux server (SL6.3). Switching to the current "alpha" version on Mar/18/2015 resolved my problem, but my test might be too simple to answer the original question:

I tested the standard mds function at matlab R2014b as

mds_server = getenv('KSTAR_PCS_MDS_SERVER');
mdsconnect(mds_server);
status = mdsopen('kstar',shot);
  [str,ier] = mdsvalue('\T0_STR')

\TO_STR is supposed to read as a string.
If I use old version (MDS+ 6.1.26) for this command, mdsvalue() returns

  str= [1x1 java.lang.String]

which is not good. If I switched to the alpha,

  str =  '2014/08/11 14:06:37.898561'

FYI: Browsing the history on malab/NATIVEvalue.m, I found the fix has been applied quite recently so I suspect any "stable" version available at mdsplus.org does not reflect the fix.

I have just committed the fixes that were applied only to the alpha release back into the current stable releases so new stable kits will contain these fixes.
