I have used the Matlab demo (\Samples\Automation Server\MATLAB\CreatePlotInOrigin.m) which works perfectly. But this demo does not show how to get data back from Origin into Matlab. Does anyone know how to read data out of an Origin worksheet into Matlab using the automation server?

The example you cite uses PutWorksheet method to send data array to Origin. Use the GetWorksheet method for the reverse.

Greg,

thanks. GetWorksheet works perfectly.

(1) Send variable mdata to Origin:
invoke(originObj, 'PutWorksheet', 'Data1', mdata);

(2)Read data back into matlab
val=invoke(originObj, 'GetWorksheet', 'Data1')

Is there anyway to only pull specific columns using the GetWorksheet command? I'd hate to pull everything into Matlab if I only have 2 columns that I need to have pulled in there.

Hi,

See this wiki page:
http://wiki.originlab.com/~originla/wiki/index.php?title=OriginCOM:Application-GetWorksheet
for details on how to specify start/end rows and/or start/end columns.
