Hi Ming,
Try to read your xlsx data using this command "xlsread"
type 'doc xlsread' in matlab command line to see its details.
Then type 'cftool' so that matlab curve fitting toolbar opens you can chose your fit, and when you're satisfied you can go to 'File > Generate Code' and save it as an .m file.
Then take a look inside the created m file and i'm sure you'll learn how to do it without curve fitting interface ;)
Good Luck!

Could you successfully read the xls file and create 25 set of data?

Hello, Please go though the 'fit' and 'polyfit' function help in matlab. These might address your query. http://www.mathworks.in/help/curvefit/fit.html and http://www.mathworks.in/help/matlab/ref/polyfit.html and the corresponding related functions too.
Please let me know in case of any further queries.
Regards, Pratik
