what version of MATLAB are you using, looks like you are referring to this link

http://www.mathworks.com/matlabcentral/fileexchange/2855-xlswrite, if that is the case you need to download the corresponding file from file exchange

Well I don't know ....

   xlswrite(filename,A,sheet,range)

... the order of arguments ??? what do you think about ?

[Amit]

I think we can use this order also where m is matrix xlswrite(m,header,colnames,'myfile.xls')
