Hello,
I have a simple question. When I try read to real-time Excel data, xlsread doesn't work, meaning every new request does not give me real-time data. However, the following 2 lines do ...
s = ddeinit('Excel', 'q.xlsx');
t = ddereq(s, 'r1c1:r1c2');
So, I'm just curious, why doesn't xlsread work? And why does ddeinit etc. work?
Thanks
Damo
