Hi,
I am dealing with a spreadsheet which is linked to Bloomberg and therefore it is updating like every 1 min or so. I would like to find a way how i can automatically import the spreadsheet into a Matlab table every time the Spreadsheet data changes. Any suggestions how i can proceed on this issue?
best regards,

It is possible to use a macro in excel that will tell matlab, in some way, if it has been updated.
It is also possible to just check the spreadsheet, from matlab, every "n" seconds. ("pause" & xlsread, being the commands you'd want)
It is also possible to control the spreadsheet's operation from matlab via an active x server.

It depends what you're doing.
This:
tic
do stuff
a = toc;
Makes "a" store how long it took to "do stuff".
now & clock both return the current time, so you can calculate how long it took to:
a = now; or clock...
do_stuff
b = now; or clock...
time_taken = b-a;
With those you can make sure you only read the excel file at specific times. (say, once every minute, at 25 seconds.)
