HOW To Import Data from Excel to matlab - BALAJI RAMAN - Mar 16 18:25:00 2004

Hello everybody,

This is my first mail to the group.

I need some help on importing data from excel..

I am not that good at matlab..

I have certain data sets in excel and i would like to plot the x and
y values..

Is there some way that i can access excel files through matlab..

These data sets are huge.

Thanks In advance

Balaji

I usually export the Excel spreadsheet as
space-delimited text document and import the created
file into Matlab using the "load" command. Of course,
I'm making it sound easier than it really is.

If the exported text file is more complicated than
just two simple columns, then you may have to read the
data line-by-line.

First you open the file using:

fid = fopen('myfile.txt');

then read the data with the "fscanf" command.

Finally, you close the file:

fclose(fid);

Again, I'm making it easier than it really is. --- BALAJI RAMAN <>

You may try to use "xlsread" Matlab command as well.

better way is to use functions 'xlsread' and 'xlsfinfo'. refer to matlab help
(help xlsread) for details.
