Hi,
I am trying to read some data using xlsread. It is giving following 
msg-
Unable to read XLS file C:\MATLAB6p5\work\test.xls. File is not in
recognized format.
Error in C:\MATLAB6p5\toolbox\matlab\iofun\xlsread.m
biffvector = biffread(filename);
Error in C:\MATLAB6p5\work\readfile.m
ax=xlsread('test.xls');

Can anyone help me on this.
Thanks.

Hello Suyash

Difficult to say without seeing the "test.xls" file............But Please
check.....

1) Directory of  the 'test.xls' file? Is the path name correct?
2) Is the original file in 'xls' format?
3) Try matlab function 'csvread'  and check the result

Regards

Is your test.xls really xls file or you just renamed from other file types to .xls? I
think if you created it by Excel and saved as .xls, xlsread should can open it correctly.
   
  Hope this helps.
