Dear EdgeMe,
ReplyDeleteI am new to matlab, am and in the process of switching over to freemat becos the pricing of matlab is ridiculous. I love your blog becos you use freemat code for the exact purpose I need: study of financial markets.
I have a serious question. I have a live data feed into excel ( by dde or rtd), how do I transfer that live feed into freemat, so that I can chart and do analysis in realtime?
Good job! I like your post, it is very short but so informative and useful too.watch here
