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 spacedelimited 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 linebyline. 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.

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.  "Juan I.
