MATLAB Central Newsreader - exporting processed singnal using 1 D wavelet

exporting processed singnal using 1 D wavelet

ammal — Thu, 20 Dec 2007 12:23:36 -0500

Hi All,
I am processing a 1-D signal using wavelet. i am wondering
how would i export the processed signal (not the figure) to
be able to read the data in Excel.

Thanks,

Ammal

I'd probably start by looking at XLSWRITE and/or CSVWRITE, and if those
didn't do what you want I'd look at some of the other file I/O functions
listed in "help iofun".

Alternately, if you're planning to use Excel to perform some analysis on
your signal, I'd look and see if MATLAB has the capabilities you need to
perform that analysis and skip Excel altogether. I may be a little biased,
though :)

Would you please explain what XLSWRITE is. I just need to
get the data for which the figure is given by wavelet so i
can perform other analysis.

Type "help xlswrite" without the quotes at the prompt. That will give you
the M-file help for the XLSWRITE function; you can do the same thing with
CSVWRITE or just about any function in MATLAB. If you want more information
than what's in the M-file help, use "doc xlswrite" (again without the
quotes.)

I'm not sure I exactly understand what you're trying to do -- are you trying
to take some data, that you've plotted, and put it into Excel; are you
trying to take a figure that someone gave you, extract the data, and put it
into Excel; or are you trying to do something else (in which case, please
describe what you're trying to do in more detail.)
